渦のある翼間流れの数値シミュレーション Flow Patterns Induced by Vortices 西村, 英明 NISHIMURA, Hideaki When located in a confined region, vortices form a flow field in the region of mutual interference. The obtained flow field is very useful in the analysis of the secondary flow in a cascade. In this report three flow patterns are calculated by using the elliptic functions and hyperbolic functions. The flows are in; 1) a parallelogram bounded by four boundaries, 2) a channel restricted by upper and lower boundaries, 3) a half region confined by upper, lower and left boundaries. The method of vortex distribution in a calculation plane and the calculated results are also shown. A few comments on the characteristics of the elliptic functions are presented in the appendix. It is concluded that this method is effective in analysing the secondary flows with vortices in a cascade. 資料番号: NALTR0932000 レポート番号: NAL TR-932 technical report 航空宇宙技術研究所 National Aerospace Laboratory(NAL) 1987-05 application/pdf 航空宇宙技術研究所報告 932 13 Technical Report of National Aerospace Laboratory TR-932 0389-4010 https://jaxa.repo.nii.ac.jp/record/45191/files/naltr00932.pdf https://jaxa.repo.nii.ac.jp/records/45191 eng
