Abstract

In India, we receive almost 80% of continuous solar radiation yearly. In order to make maximum use of this solar insolation, there are various solar thermal technologies of which one is concentrating solar power (CSP). Solar cavity receivers are more efficient technology as compared to solar trough technology. However, due to the complex design and losses in heat transfer in the form of convection, solar cavity systems have fallen behind in the world of alternative energy systems. In order to make cavity receiver technology more efficient various energy losses are to be considered and efforts should be made to minimize them. The parabolic concentrator reflects the direct incident solar radiation onto a receiver mounted above the dish at its focal point. The conversion of concentrated solar radiation to heat takes place in receiver. The heat transfer characteristics of the receiver changes during the rotation of the receiver which affects thermal performance. A heat transfer and flow simulation is performed for different solar cavity receiver’s viz.: cylindrical, cubical, conical, dome and spherical receivers at various receiver inclinations at constant temperature. The receivers are designed such that they have same surface area and aperture. It is observed that convective heat loss decreases as the inclination changes from 0° to 90°. Among these receivers, the convective heat loss for different geometries & different angle of inclinations are studied.
