... around the circumference of the absorber tube wall. This study proposed an efficient step-by-step procedure incorporating the Monte Carlo ray-tracing (MCRT) and finite volume approach for the design procedure. Gong et al. [ 27 ] enhanced the flux distribution by using a secondary reflector (SR) as a flux...

..., hybrid ray-tracing (HRT), surface property simulation, and sky model. The HRT can achieve high accuracy using significantly fewer computation resources compared with Monte Carlo ray-tracing (MCRT) and was validated against tracepro . The new optical model incorporates angular and spectrum dependence...

... position, without or with little restrictions. A nonsimplifying ray-tracing tool is used for the performance evaluation. During the optimization, detailed local weather and site characteristics (e.g., topography) can be considered. An example case is presented and discussed. This case is based on a field...

Since ray-tracing is a statistical method of tracing the sunrays from the reflector to the receiver, it is unavoidable that the simulated results obtained in our study are also statistical data...
