| Research Abstract |
In this study, fast and precise simulation techniques to simulate complex heat and fluid flows in wind tunnel tests were developed to obtain detailed information from wind tunnel experiments. For example, time-series of inflow velocity fluctuation measured in wind tunnel tests were modeled with random Fourier modes and applied to the simulations to reproduce the realistic turbulent inflow. The effectiveness of the method was confirmed by the comparison between experiments and simulations of the starting process in a shock tunnel and by the prediction of complex flow and heat transfer fields at the leading edge of a symmetric airfoil in a low speed wind tunnel.
