The temperature gradient and concentration gradient were both large in the near - wall region. although the thermophoresis force could affect the 50 - micron particle, the concentration did not change as large as 2 - micron particle because of the large mass and the wall effect
熱泳力對粒徑為50微米的顆粒也有影響,但是由於顆粒的質量較大,再加上壁面效應,其作用效果遠沒有2微米顆粒明顯,僅在近壁區顆粒的濃度略有升高,而其它部分基本不變。
The temperature field along the axis, axial velocity, the turbulent energy, and the concentration of the particles were investigated when the temperature field varied. the numerical experiment shows that the thermophoresis force changes the concentration of the 2 - micron particle, decreasing in the main flow and increasing in the near - wall region
數值實驗的結果表明在兩相流模型中添加熱泳力源項會對2微米顆粒在流場中的濃度分佈有很大的變化,主流區的顆粒濃度降低,近壁區顆粒濃度在溫差不大的時候,提高幾十倍。
