The porous wall acts as a kind of seine for separating molecules 多孔壁的作用就象一把篩子
Experimental investigation of the heat transfer for transpiration cooling through a sintered porous plate 燒結(jié)多孔壁面發(fā)汗冷卻換熱的實驗研究
The cooling effectiveness of effusion cooling in the regions with holes and downstream the last row of holes on hot side is much higher than that of conventionary film cooling with the same operation conditions 在熱側(cè)面上的氣膜孔區(qū)及其下游區(qū),致密多孔壁的冷卻效果都非常好,比同等條件下常規(guī)氣膜冷卻的效果好得多。
To investigate the influence of porosity of holes array on cooling effectiveness of an effusion cooled plat plate , a numerical study of the distributions of cooling effectiveness on the hot side of an effusion cooled flat plate was carried out with four different porosities of holes array 摘要為了獲得氣膜孔陣排列的疏密度對致密多孔壁冷卻效果的影響規(guī)律,分別對四種疏密度排列下的平板熱側(cè)面上的冷卻效果進(jìn)行了數(shù)值模擬研究。
