A numerical study on optical and thermodynamic characteristics of a spherical cavity receiver

•Monte-Carlo Ray Tracing Method and CFD model are established and combined.•Spherical cavity receiver has better optical performance than other receivers.•The heat loss of spherical cavity under different conditions are analyzed. In this paper, a 3D model is created to investigate optical and thermo...
