    Abstract: 本研究利用自行研發的DSMC平行模擬程式PDSC++[1],以歐洲太空返回實驗艙-專家號EXPERT (European eXPErimental Re-entry Test-bed) 進行真實三維的流場模擬。實驗艙於高速稀薄流場飛行時,它的外部流場有震波、紊流及邊界層等氣動力之問題需要瞭解與克服。此外在極高的飛行速度下,載具與大氣發生劇烈的交互作用,在艙前段震波之後產生極高的溫度,在此高溫下,氣體很可能會發生各種化學反應,使得氣體的組成也都發生變化。因此,本研究主要針對不同的飛行高度(圖1)、飛行速度與攻角(圖2)所引起之太空載具相關熱化學反應與氣動力(圖3)的驗證與分析,模擬所得結果,將可提供未來太空載具研發的基礎資料庫與分析能量。
