In order to study the effect of scattering error on concentrating performance of dish solar energy collector
the Monte Carlo ray-tracing method was used to calculate the concentrating reflection.The distribution of heat flux of the reflected light to the collector end face is studied
and the heat flow density distribution differences when the scattering error is 1.75 mrad
2.50 mrad
5.00 mrad and 10.00 mrad were compared.The result indicates that
at the collector end
the heat flux density is close to the circular distribution.With the increasing scattering error
the distribution of the heat flux distribution tends to disperse.The lower the heat flux
