The general flow characteristics are well known, at least for jets expanded into a stagnant gas. Detailed and precise prediction is, however, very difficult, even numerically. In the present paper, the continuum free-jet flows expanding into stagnant and flowing gases are analyzed numerically by the Piecewise Linear Interpolation Method (PLM). It is found that the flow structures depend very much on the pressure and the flow Mach number of the ambient gas. A few of the numerical results are compared with the experiments., 資料番号: NALSP0007021, レポート番号: NAL SP-7}, title = {数値計算による自由噴流の特性の研究}, year = {1986} }
