Numerical study of wind pressures on a Domed roof and near wake flows
AbstractUnsteady wind flows and pressures around a dome-shaped structure are investigated from the computer simulation. We obtain the three-dimensional numerical solutions by the direct integration based on the finite difference technique of the incompressible Navier-Stokes equations in the generalized coordinate system. No turbulence models have been incorporated and the third-order upwind scheme for the convection terms has been adopted in the present numerical procedure. In order to confirm the accuracy of the computational results, we have compared the numerically-computed aerodynamic characteristics obtained through the time-averaging with the experimental data. We also bring into focus the pressure distributions acting on a domed roof and the near wake flows. Their fluctuating characters are discussed in detail.
