@techreport{oai:jaxa.repo.nii.ac.jp:00043148, author = {小川, 哲 and 石黒, 登美子 and Ogawa, Satoru and Ishiguro, Tomiko}, month = {Nov}, note = {A numerical procedure for solving the flow field generated by a moving body is presented based on a finite difference solution of Navier-Stokes equations. A conservation-law form of the equations in a general time-varying coordinate system is derived from the Cartesian expression by applying the concept of Lie derivatives. Specifically, a moving coordinate expression of the streamfunction-vorticity formulation is derived, and is used for the analysis of the dynamic-stall phenomenon of an oscillating airfoil in incompressible flow. A computation example is given for an NACA 0012 airfoil oscillating in pitch at an amplitude of lO degrees about a mean angle of attack of 15 degrees with a reduced frequency of 0.4pi and a Reynolds number of 2 by 104 based on the chord length and the uniform advance speed of the airfoil., 資料番号: NALSP0003006, レポート番号: NAL SP-3}, title = {非定常ナビエ・ストークスの数値シミュレーション}, year = {1984} }
