321 Real-Time Analysis of Kalman Vortex Street Using Hybrid Wind Tunnel
Details
It is difficult to obtain accurate and complete information of real flows by either numerical analysis or experimental measurement. Especially, determination of the pressure field in real flows is critically difficult problem. Hybrid wind tunnel integrating the numerical simulation and the measurement is possible solution to this problem, but has been investigated as off-line analysis tool. In this paper, we improved the hybrid wind tunnel system to obtain the accurate pressure, and to perform the real-time analysis. Karman vortex street behind a square cylinder was investigated with new system. Comparison between the measurement and the analysis for the pressure at feed back point shows good agreement.
