乱流境界層風洞の数値シミュレーション

Abstract

A boundary layer wind tunnel was simulated numerically. The three-dimensional simulation method of turbulent boundary layer over rough surfaces, using a refined k-e turbulence model was examined and it applicability was shown by comparing the numerical results with the experimental data. Using the simulating method described here, wind characteristics over rough surfaces and the effect of incident flows on a square cylinder were examined numerically. The good applicability of the simulation reults indicats that these preliminary calculations could be a powerful tool in the design of actual wind tunnel tests and the inlet conditions having various wind characteristics can be created by this method.
