ABSTRACT:
Uniformity of flow and collection efficiency within a distributed field of concentrating collectors have been evaluated experimentally. The results give a quantitative explanation for the nonuniformity among collector outlet temperatures which has been detected over years of system

operation. such temperature nonuniformity reduces system performance, and can cause degradation of heat transfer fluid. This investigation was conducted on one row of five collectors of the 113 active parabolic dish collectors at the Solar Total Energy Project in Shenandoah, Georgia. Test results show significant nonuniformities in the optical, thermal and hydraulic performance among these collectors. These nonuniformities cause significant differences in the individual collector outlet temperatures. Show Less
