Abstract

Based on LOS method ,combined with DSMC, the particle clouds movement model and the optical radiation transmission model were established, the dynamic radiation performance and transmittance of particle clouds in space within medium wave and long wave were analyzed accordingly, the results showed that the heat flux in space has a certain influence on the particle clouds radiation, but not on the extinction obviously; when the number density of particle clouds was greater than 1x10⁷ , the transmittance of particle clouds in medium wave and long wave was less than 10%.
