With abundant solar radiation resource, land resource advantage of desertification in northwest areas of China is the ideal place to build solar thermal power stations, however, these areas at the age of wind, sand and dust weather also to safe and reliable operation of the solar thermal power generation equipment produced adverse effect. By numerical simulation, currently the most widely used RP-3 type collector surface wind pressure in three-dimensional steady flow field characteristics and the settlement of sand dust in two phase flow field characteristics, simulated and analyzed the windward angle and wind speed is obtained for slot pressure and the surrounding dust collector surface subsidence rule of the influence of the relationship. The conclusion of changing wind angles had no effect on the wind pressure coefficient of the value of windward and the changing wind angles had a great effect on the wind pressure coefficient of the value of leeward; when the different angles, surface of the collector and the flow field around the dust volume fraction changes have a big difference. This study is suited to the characteristics of the climate in our country groove collector in the efficient operation of wind environment provides certain theory basis.
