: Current research on photovoltaic generators is focused on improving operational efficiency and ensuring a long-life service, previous studies indicate that the degradation of photovoltaic generators generally results from the stress of various climatic factors in the natural environment; Sandstorms being among them and possibly the most influential where surface erosion is generated. In this paper, a novel simulator to test wind and sandstorms blowing in the southwestern Algeria Desert is presented. The developed simulator was able to generate winds at different speeds, with varying sand grain densities. as well as we rotated the samples using 360° to allow the wind to reach them from all directions. These properties adopted in the simulator will be used in subsequent research in accelerated tests to predict and estimate the degradation under the influence of sandstorms separately from any other climatic factor. We created an actual database of sand and wind density, taking measurements during the monsoon season. the obtained results confirming in consistency with those measured. We have succeeded to estimate the photovoltaic unit lifetime, and ensure better operating conditions.

This The energy performance of photovoltaic solar power plants under real environmental conditions is the main objective of manufacturers and operators. Improving its performance requires continuous monitoring to examine and evaluate the condition of different parts of the station and identify various potential faults. In this study, we will highlight the aggressive effect of sand winds which blow in the presence of high temperature on the connectors which ensure the connection between the photovoltaic modules; we will model and evaluate the temperature of the 2 connectors, one with sand and the other without sand. Based on previous experimental data for two connectors in a thermal oven, each of them connected to a branch of an electrical circuit consisting of a DC power source, a shunt resistor and a DC lamp, bonded on each wall of the connector a thermocouple to measure the temperature, the modelling results show that the temperature of the connector with sand is higher than that without sand.

<abstract> <p>In this study, we will shed light on the aggressive effect of a blowing sandstorm in the presence of high temperatures on the photovoltaic inter-module connectors in a solar station located in the desert environment of southwestern Algeria. After a short period of operation, it is observed that the MC4 connectors, which tighten the interconnection between the photovoltaic modules, are completely faulty because of sand grains carried away by a wind blowing at an average annual speed, which exceeds 6 m/s. Then, we analyzed and evaluated the connector failure to propose an appropriate solution. We checked the variations of the intrinsic temperatures of each connector employing the thermocouple for the three cases of operating temperatures, as well as the current measurement flowing through each connector, to calculate the powers dissipated in each branch of the circuit. Finally, this experimental work shows that a loss of power reaches almost 10% from the nominal power of the typical case. The proposed solution for this problem is to cover the connectors with an impervious plastic cover.</p> </abstract>

During a forced convection sun drying and storage operation, the equilibrium water content of a product to be dried is critical. These figures are frequently derived using isothermal sorption curves. The calculation of isotherms is a necessary step in determining the distribution and intensity of water connections in products. for that this paper concentrates on the experimental determination of the adsorption-desorption isotherms for various temperatures (40, 50, and 60℃) of the Nicotiana Tabacum L plants. From which we had established the relationship between the water activity and the water content in the product. However, the aforementioned determination was carried out by the static gravimetric method. Eight saturated salt solutions have been utilized in applications such as (KOH, KCl, MgCl2, MgNO3, K2CO3, BaCl2, K2SO4, and NaCl). Hygroscopic equilibrium was completed after 13 days for temperature 40℃, 11 days for 50℃, and 9 days for 60℃. The overall experimental sorption curves are summarized by six models (HENDERSON, modified HALSEY, OSWIN, GAB, modified BET, and PELEG). The sorption isotherms built using the Clausius–Clapeyron equation were used to determine the net isosteric temperatures of desorption and adsorption of Nicotiana Tabacum L. The results for the adsorption-desorption isotherms found are type III according to IUAPC. Following the smoothing of the experimental results by different used models, it was found that the models of GAB and Peleg allow having the lowest mean relative errors and correlation coefficient.

In this study, a three-dimensional (CFD) model is employed to simulate and optimize the CCS (Channel Cross-Section) shape of the single straight channel PEMFC. Four CCS shapes, namely trapeze, inverted trapeze, half of ellipse and inverted half of ellipse, are investigated using ANSYS-FLUENT software and compared to the rectangular and triangular CCS shapes. The results obtained from the simulation are compared to the experimental results of the literature. A good agreement is observed between the numerical and experimental results. From the obtained results, it appears that the best delivered power density is reported by the trapeze CCS configuration, whereas, the worst delivered power density is obtained by the inverted half of ellipse CCS configuration. The highest pressure-drop and pumping power are obtained with the triangular CCS configuration and the smallest are resulted by the rectangular CCS configuration. Finally, the highest net power output is reported by the trapeze channel cross-section configuration, while, the lowest one is yielded by the inverted half of ellipse CCS configuration.

Received: 18 April 2019 Accepted: 10 July 2019 The equilibrium water content of a product to be dried is essential during a forced convection solar drying and storage operation. These values are often taken from the so-called isothermal sorption curves. The isotherms determination is an essential step to know the distribution and the intensity of the water connections in the products. They make it possible to determine the products final water content to be reached in order to optimize the drying conditions and give valuable information on the hygroscopic equilibrium. As a result, this experimental study aims to determine the physicochemical components' and the desorption isotherms curves for deferent date type L’hmira, Bamakhlouf and Tegazza from the Touat region, in South-West Algeria, using the saturated salt solution method. The experiment is carried out for three temperature values 40 ° C, 50 ° C and 60 ° C, to study the influence of the temperature on the equilibrium curves of the product and finally to describe the isothermal moisture desorption for deferent date types for three temperatures using known models of GAB, SMITH, LANGMUIR and OSWIN.

Received: 22 July 2018 Accepted: 14 September 2018 The Purpose of the paper is studied three types solar distillers, double slope with and without immersed fins and the simple solar distiller. A monthly comparative study is investigated experimentally, for a long period of the year. Further, the wind speed influence, the distance between fins, the fins height, the fins number and thickness, on the solar distiller’s production, is investigated theoretically. From the obtained results, it is noted that for the wind speed greater than 3.5 m/s, a decrease in the productivity is caused by the cooling of the outer walls, and this induces some heat losses, especially at the front and rear walls of the solar still. The distance between fins has no significant effect on the still productivity. Moreover, increasing the fins height, from 2 to 5 cm, increase the productivity; however, when the height changes from 6 to 8 cm, the distillate production goes down. A larger fins number lead for rise the produced distilled water amount. Therefore, one should use the maximum number of fins, while taking into consideration the feasibility of the assembly. Increasing the water mass makes the productivity to go down. The obtained results on June 11, 2016, show that the proposed system productivity was about 15 to 27 % higher than that of a simple one, under the following conditions, i.e. Mw = 42.61 kg, h1 = 3.6 cm, Vw = 3.5 m/s, lw = 5 cm and Nfins = 12. The total annual cost estimation proof clearly that the payback period is less than a years. As well as, it has been found that the increasing lifetime and the interest rate decreasing caused a decrease in the distilled water unit price.

This work presents a theoretical and experimental study of a double slope still with fins immersed in a basin. The influence of the speed of wind, distance between fins, height of fins, number of fins and thickness of the water layer in the basin, on the production of the still, is investigated. From the results obtained, it is noted that for a wind speed greater than 3.5 m/s, a decrease in the productivity is caused by the cooling of the outer walls, and this induces some heat losses, especially at the front and rear walls of the still. The distance between fins has no significant effect on the still productivity. Moreover, increasing the height of fins, from 2 to 5 cm, causes a raise in the productivity; however, when the height changes from 6 to 8 cm, the distillate production goes down. A larger number of fins lead to a rise in the amount of distilled water produced. Therefore, one should use the maximum number of fins, while taking into consideration the feasibility of the assembly. Increasing the mass of water in the basin makes the productivity to go down. The results obtained on June 11, 2016, show that the productivity of the proposed system was about 15 to 27 % higher than that of a simple one, under the following conditions, i.e. mw = 42.61 kg, h1 = 3.6 cm, Vv = 3.5 m/s, lw = 5 cm and Nfins = 12.
