【 摘 要 】

The erosion wear behavior of dust on the surface of PV modules in desert aeolian gas-solid two-phase flow was analyzed by discrete phase model.This paper investigated the effect of the tilt angle the wind speed the particle size the mass flow to erosion on PV modules surface.The conclution showed that the tilt angle and the wind speed are the major factors to effect the maximum and average erosion rate on PV modules surface. In especially,the effect of wind speed on the surface erosion rate of PV modules varies exponentially.
