In conventional studies on the Crookes radiometer, the vane temperature was assumed to be higher at the black side than at the shiny side. In this study, a new idea - the vanes are isothermal but accommodation coefficients are different at the black side αB and the shiny side αS - has been proposed and examined using DSMC. Higher gas temperature and pressure are induced at the black side with αB=1 than at the shiny side with αS<1, acting as a force to push the vanes.
