摘要
Abstract
Pressure response of two-dimension multiphase thermal insulation material with fiber diameter of 1.25 μm,2.5μm,10μm have been analyzed with DSMC approach at different internal-external pressures. The purpose of this study is to investigate effects of fiber diameter, aperture ratio, internal-external pressures and macrocosmic material thickness on pressure response. The results show that at the same conditions, response time increases as aperture ratio and fiber diameter decreases, respectively. Influence of the ratio of internal-external pressure on response time is not obvious. The ratio of internal-external pressure increase, response time increase a little. At the same ratio of internal-external pressure, response time tends to be close.关键词
