| Abstract |
An experimental study on energy density distributions produced by dish solar concentrating system was performed to optimally design and rightly position a cavity receiver. This deemed also very useful to find and correct various errors associated with a concentrator. It is observed that the actual focal length is 2.17m with a maximum energy density of 1.89MW/m2. By evaluating the position of flux centroid, it was found that there are errors within 2cm from the target center. As a result of the percent power within radius, approximately 90% of the incident radiation is intercepted by about 0.06m radius. The area concentration ratio normalized to 800W/m2 insolation and 90% mirror reflectivity was 347 suns. The total integrated power of 2467W was measured under focal flux distributions, which corresponds to the intercept rate of 85.8%. |
