Nanofluids which act as coolants in various thermal applications have been promising in accomplishing the primary objective of heat transfer. However, the impact of such fluids on flow lines in the form of enhanced friction factor through unacceptable viscosity rise is an issue to be addressed. On the other hand, these fluids are expected to deteriorate the environment when used or disposed. Hence this research focuses on preparing a bionanofluid and investigating on its primary properties, the thermal conductivity and viscosity. The bionanofluid is prepared by dispersing neem (azadirachta indica) assisted zinc oxide nanoparticles in a binary mixture of ethylene glycol-water (50:50 by volume), at volume concentrations of φ=0.05, 0.2 and 0.5%. To compare the properties of these bionanofluids, additional nanofluids were prepared by dispersing combustion derived pure zinc oxide at same volume concentration. By XRD analysis, the average crystallite size of neem assisted ZnO and pure ZnO was found to be 36 nm and 32 nm. Based on the SEM images, the particles were found to be much closely packed in bioparticles than combustion derived ones. The zeta potential of the nanofluids was found to be 30 mV at pH 6.5, at which the stability is deemed excellent. The thermal conductivity and viscosity of the nanofluids were measured under varying volume concentration and temperature ranging between 20oC and 50oC. Though the thermal conductivity of the conventional ZnO nanofluid is 3.8% higher than the ZnO bionanofluid, the viscosity is 2% lower for the latter than the former, which is highly expected from any nanofluid for an efficient thermal transport.

Solar distillation is an economical and nature-friendly method used for the product of fresh water from the (mixing of salt water and fresh water) brackish water. Solar still performance depends mainly on the absorber plate conditions. Since all the solar radiation is mainly absorbed by the basin plate and the water present in the basin. In this experimental work, the performance of the basin plate is enhanced by using diverse basin plate configurations with energy storing materials like mild steel, black gravel, pebbles, sand, and cast iron. The basin plates and the energy storing materials increase the evaporation area and it will store the high heat during the sunshine hours and emitted the stored energy during the off shine hours to the system enhances the still productivity in the less solar radiations too. Here, the comparison has been made between the energy storing materials with flat absorber plate to the trapezoidal and the pin fin absorber plate with similar conditions. Through this experimentation process, we could conclude that trapezoidal basin plate with varied energy storing materials plays a predominant role in the production of distilled water than the flat and pin fin basin plates. On the other hand, black gravel gives good productive results compared to other energy storing materials used in this experiment for all basin plates. This will show the fulfilment of the basin plate and the productivity could be enhanced with different configurations of basin plates as well as incorporation of different energy repository materials

ABSTRACT The double pass collector is one of the most efficient means of drying crops because heating of air takes place from both sides of the absorber plate. To investigate the performance, a double pass natural convection solar dryer was fabricated for experimentation; the results were collected and used to develop a validated numerical model using MATLAB. The experiments were undertaken during February–March 2016 in Salem Tamil Nadu, India over 10 sunshine days. The simulation was carried using the developed model under the measured ambient conditions. The results showed that the mathematical model could predict the performance of the double pass collector for a particular ambient condition to an uncertainty of ±5%. This model could be used to optimise the performance of the collector so that we can predict and investigate the actual performance of the collector with the various optimised designs before fabricating the dryer.

ABSTRACT Biodiesel is a promising fuel for compression ignition engines instead of diesel fuel. Due to the depletion of diesel fuel, an alternative fuel can be used in an engine. The experiments were conducted on a four-stroke, single cylinder CI engine. In this present investigation, an attempt has been made to study the influence of injection pressure (IP) and injection timing (IT) on the performance and emission characteristics of diesel engines by using mixed biodiesel (Thevetia peruviana, Jatropha, Pongamia, and Azadirachta indica). The injection pressure is varied from 200 to 230 bar and the injection timing is varied from 23 to 29° bTDC at an increment of 10 bar and 2° bTDC, respectively, and the results were compared with diesel. From this study, the results showed that the brake thermal efficiency (BTE) was increased by 2.4% with an increase in injection pressure and 1.5% with an increase in the injection timing for the maximum load, but lesser than diesel. Furthermore, a reduction of 5.08% of brake specific fuel consumption (BSFC) has been noticed for the rise in IP and IT with loads but higher than diesel. The reduction was 34.17%, 53.85%, and 29.7% and 29.17%, 53.85%, and 21.95% of hydrocarbons (HC), carbon monoxide (CO), and smoke emissions, respectively, at 230 bar injection pressure and at 27° bTDC injection timing. Also, a significant increase in nitrogen oxides (NOx) and carbon dioxide (CO2) emissions at the maximum load was observed by increasing the injection pressure and injection timing.

In the present work, the biodiesel from non-edible neem oil (Azadirachta indica) is prepared by the method of two-step ‘acid-base’ process. An experimental investigation has been carried out to analyze the performance, emission, and combustion characteristics of a diesel engine fueled with neem oil methyl ester and its blends (10, 20, 30, 50, and 100%) vis-à-vis diesel at different loads and constant engine speed. The performance parameters evaluated include brake thermal efficiency; exhaust emissions, including CO, HC, NOx, and smoke intensity; and combustion parameters, including cylinder pressure and instantaneous heat release rate. Lower concentration of neem oil methyl ester in the blend gives better engine performance, combustion, and exhaust emissions. The experimental results proved that the use of neem oil methyl ester in diesel engines is a viable alternative to diesel.

An experimental investigation has been carried out to evaluate the effect of using diethyl ether as an additive to biodiesel on the combustion, performance, and emission characteristics in an unmodified diesel engine at different loads and constant engine speed. The results indicate that peak cylinder pressure and heat release rate is higher for 5% (by vol.) diethyl ether blended biodiesel than those of neat biodiesel. The carbon monoxide and smoke emissions decrease while oxides of nitrogen and hydrocarbon emissions increase for 5% diethyl ether blend than those of neat biodiesel. The brake thermal efficiency of 5% diethyl ether blend is higher as compared to biodiesel.

JSW Steel Limited, Salem Works (JSWSL), is an integrated steel plant, having a production capacity of 1.0 mtpa (million tons per annum) of high-grade automotive special steels. At JSWSL, hydrogen induced cracks and center unsoundness contribute more to UT (Ultrasonic testing) rejections in chrome-molybdenum (Cr-Mo) and high manganese grade steels. Hydrogen induced cracks was controlled by increasing argon flow rate from 3-4 Nm3 to 7-9 Nm3 during vacuum degassing. Vigorous purging led to a reduction in hydrogen levels from around 2 ppm (parts per million) to less than 1.5 ppm. Center unsoundness was controlled through optimising superheats in tundish. Data of trial heats revealed that, UT rejections were more in heats cast with superheat levels more than 35°C. Based on the data obtained from trial heats superheat was optimised to 25-35°C for both Cr-Mo and high manganese steels. The present paper discusses the measures taken to reduce UT rejections in these grades.KeywordsJSWSL, Cr-Mo, High Mn steels, UT rejections, superheat, hydrogen induced cracks, center unsoundness, vacuum degassing, continuous casting.

The research is aimed to optimise the engine parameters by using biodiesel as a fuel. Neem oil is used as a bio diesel in CI engine which is produced by transesterification process. Taguchi optimization technique was used to get optimum level of parameters such as brake thermal efficiency (BTHE), indicated thermal efficiency (ITHE) and specific fuel consumption (SFC). Experiments were conducted with neem oil biodiesel blends and diesel value were compared with these results and presented in this paper. The result clearly shows that blend B60, compression ratio 18:1 and 6 Kg load was the optimum parameters.Keywords: Neem biodiesel; CI engine; Performance; Taguchi technique;

An experimental investigation has been carried out to evaluate the effect of using ethanol as additive to neem oil methyl ester on the combustion, performance, and emission characteristics of a diesel engine at different loads and constant engine speed. From the combustion analysis, it is found that the ignition delay increased with higher proportion of ethanol in the blends; maximum cylinder pressure and maximum rate of heat release increased with the increase of ethanol proportion in the blends. From the emission analysis, it is found that at higher engine loads, CO and smoke emissions are found significantly lower when operating on biodiesel–ethanol blends, but HC emissions are found higher. The NOx emissions initially increase with the addition of ethanol in the blends and then decrease with further addition of ethanol.

Fuel crisis and environmental concerns have led researchers to look for alternative fuels of bio-origin sources such as vegetable oils, which can be produced from forests and oil-bearing biomass materials. Vegetable oils have energy content comparable to that of diesel fuel. Straight vegetable oils posed several operational problems and durability problems when subjected to long-term usage in compression ignition engine. These problems are attributed to higher viscosity and lower volatility. In this study, performance and emission parameters of a diesel engine operating on neem oil and its blends of 5, 10, 15 and 20 vol% with ethanol, 1-propanol, 1-butanol and 1-pentanol are evaluated and compared with diesel operation. The results indicate that the brake thermal efficiency is improved with the use of neem oil–alcohol blends with respect to those of neat neem oil. The smoke intensity, CO and HC emissions with neem oil–alcohol blends are observed to be lower with respect to those of neat neem oil at higher loads. The NO x emission is very slightly reduced with the use of neem oil–alcohol blends except for the neem oil–ethanol blend compared with that of neat neem oil.
