[ 1 ] - An experimental investigation of performance of a 3-D solar conical collector at different flow rates
The shape of a solar collector is an important factor in solar-to-thermal energy conversion. Conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. Flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. The present study is an experimentally investigated of the performance of the solar coni...
[ 2 ] - Experimental Investigation of the Efficiency of a Semi-Spherical Solar piping Collector
Solar water heaters are good tools for saving fuel. The main component of these water heaters is collectors, which are responsible for absorbing solar energy and transferring it to the working fluid with the least heat dissipation. The present study is an experimental study of the performance of the solar semispherical collector with 1 m2 of absorber area at different volumetric flow...
[ 3 ] - بررسی آثار تخریبی استفاده از فناوری انرژی‌های تجدیدپذیر بر محیط‌زیست
تولید و مصرف انرژی، هر دو چالش‌هایی را برای محیط‌زیست فراهم کرده و بسته به نوع تولید یا مصرف اثرات تخریبی بر محیط‌زیست جانوری، گیاهی و یا انسانی می‌گذارد. یکی از راهکارهای کاهش این آثار تخریبی، استفاده از انرژی‌های نو و تجدیدپذیر است. در این مقاله، بررسی آثار و عوامل تخریب محیط‌زیست توسط نیروگاه‌ها و صنایع وابسته به انرژی‌های تجدیدپذیر شامل انرژی خورشیدی، بادی، زمین‌گرمایی، آبی و زیست‌توده مورد...
[ 4 ] - The effect of SiO2 nanoparticle on the performance of photovoltaic thermal system: Experimental and Theoretical approach
The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...
