Effect of Variation of Mass Flow Rate on Performance of Solar Parabolic Dish Collector with Dome-Cylindrical Receiver

Solar parabolic dish collector is one of the foremost economical technologies for energy conversion among concentrated solar energy systems. Parabolic dish concentrators use cavity type receivers at their point of focus to convert incident solar radiation into heat energy. Different receivers with cavity type designs were used to determine the thermal performance of solar parabolic dish type concentrators for various applications, such as industrial process heat, thermal power generation and water heating, etc. In the present work, thermal efficiency of parabolic dish collector is analysed with dome-cylindrical type cavity receiver by changing the mass flow rate of water. Experiments are performed on clear and sunny days in the month of April at KLEF (Deemed-to-be-University) [Latitude: 16.5° N, Longitude: 80.6° E].
