Paper Title :
Surface Pressure Variation Around Obstacle With Changing The Aspect Ratio

Abstract : The study aims to understand the surface pressure distribution around the bodies such as the suction pressure in the leading edge on the top and side-face when the aspect ratio of bodies and the wind direction are changed, respectively. We carried out the wind tunnel measurement and numerical simulation around a series of rectangular bodies (40d×80w×80h, 80d×80w×80h, 160d×80w×80h, 80d×40w×80h and 80d×160w×80h in mm3) placed in a deep turbulent boundary layer. Based on a modern numerical platform, the Navier-Stokes equation with the typical 2-equation (k-ε model) and the DES (Detached Eddy Simulation) turbulence model has been calculated, and they are both compared with the measurement data. Regarding to the turbulence model, the DES model makes a better prediction comparing with the k-ε model, especially when calculating the separated turbulent flow around a bluff body with sharp edged corner. The result shows that the transverse width has a substantial effect on the variation of surface pressure around the bodies, while the longitudinal length has little or no influence. Keywords: Rectangular bodies, aspect ratio, surface pressure distribution, wind-tunnel measurement, CFD.
