Abstract In order to study and investigate the overall performance of bio fluids for solar thermal applications, this work consists of integration of Taguchi method with Taguchi Grey Relational Analysis. The preparation of bio fluids has three levels of input control parameters such as Type of oil, Percentage of concentration and Stirrer speed. Output optimization indicators for the experiment were chosen as Thermal conductivity, Density and Viscosity. The comparative study made consists of coconut oil, sunflower oil and castor oil in the bio fluids preparation. These oils are available readily in the market and are quite inexpensive. The bio fluids are prepared by mixing the above oil with water in appropriate concentration. The experiment is run for the optimal solution using Taguchi analysis using L9 orthogonal array. The influential parameters which are significant in contributing the performance of bio fluids were studied using ANOVA table. After multi objective parametric optimization, the control parameters optimization level shows the use of Sunflower oil with 15% concentration at 15000 RPM stirrer speed produces the optimal performance. Based on the Ranking and Sum of squares from ANOVA table, it is evident that the most influential parameter is the type of oil followed by Percentage of concentration and Stirrer speed respectively.

Abstract The performance and emission characteristics of an engine that burns with Mahua biodiesel of 10%, 20% and 30% blends with diesel (on a volume basis) per unit area is investigated and compared with normal diesel fuel. The investigation is carried out to enhance the efficiency of the diesel fuel using biodiesel blends. The engine utilizes a direct injection system with a variable compression ratio. Also, the experiment was allotted with explicit injection temporal arrangement at 120 before the top dead center (BTDC) with the various compression ratios (air-fuel ratio) per unit area as 15:1, 16:1 and 17:1. Experiments were carried out at a constant speed of 1500 revolutions per minute. The results of the compression ratio relationship on brake thermal efficiency, specific fuel consumption, and emission characteristics have been investigated and associated. The mix blend 10 (B10) and the Compression ratio (CR) 17 are found to offer most mechanical efficiency at higher compression magnitude relations and it turns out to be 27.32%. Conjointly the Specific Fuel consumption (SFC) of mix B10 is found to be reduced in comparison to that of plain diesel. Emission parameters per unit area were analyzed with different various blends and different compression ratio relationships and compared with diesel fuel. The emission of Carbon monoxide oxides (CO), Hydrocarbons (HC) were generated with a rise in mixing magnitude relation and compression magnitude relations of most loads. Conjointly carbon dioxide emissions were found to be more than in diesel. The engine performance was found to be optimal once persecution of B10 as fuel at a compression magnitude relation of 17:1 throughout full load condition is when made.
