This paper presents a time-linearized time-domain solution method that includes effects due to the shock-generated entropy and vorticity and shock wave motions. The solution procedure correctly accounts for the small-amplitude shock wave motion due to small unsteady changes in the aerofoil boundary conditions, and correctly models a flow-field with embedded strong shock waves. Steady and first harmonic pressure distributions for the NACA 0003 aerofoil with a harmonically oscillating flap, and NACA 0012 aerofoil undergoing a sinusoidal pitching oscillation, are predicted and compared with the Euler results., 資料番号: AA0063824001, レポート番号: JAXA-SP-07-008E}, pages = {1--8}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Efficient time-linearized TSD computations including the effects of shock-generated entropy, vorticity and shock wave motion}, volume = {JAXA-SP-07-008E}, year = {2008} }
