The objective of the study is to investigate and optimize solar flux uniformity a fixed linear-focus Fresnel lens concentrator using triangle cavity receiver. effects receiver parameters including vertical distance from opening plane f, internal surface absorptivity αab, end reflection reflectivity ρr, declination angle δ ω on factor (UF) were carried out. are evaluated with significance test c...

2014 This report is an account of the design, checkout and solar testing of a cavity receiver using metal gas-in-tube heat exchangers. The design represents a scale model of a Brayton cycle solar electric plant receiver. The program span from initiation of design to test completion was 32 months. The DOE-Central receiver test facility was utilized in this inaugural test. Tests involved controll...
