1. 제 목 : An Analytical Asymptotic Solution Method for Efficient Flow Analysis and Aerodynamic Design
2. 연 사 : 이기동 교수 (University of Illinois, 항공우주공학과)
3. 일 시 : 2003년 6월 18일 (수) 14:00 - 16:00
4. 장 소 : 서울대 신공학관(301동) 117호 세미나실
5. 내 용 :
An efficient aerodynamic design optimization technique will be presented, which is based on an analytical asymptotic flow solution method. The analytical solution method is formulated in a streamline coordinate system, wherein the governing equations are transformed into a non-homogeneous Cauchy-Riemann system. A sequence of coordinate transformation and asymptotic expansion places the governing equations in a form suitable for classical mathematical techniques. The method has a strong potential for aerodynamic design application, since the objective function can be evaluated at a very low computational cost. The efficiency of the method is demonstrated for flow analysis and inverse design of airfoils and airfoil cascades.
