【Abstract】 In this paper the finite analytic method and K- e turbulent model for low Reynolds number are employed to solve Reynolds equations. In two cases of Reynolds number being 104 and 106 , the turbulent flow past a flood discharge tunnel is calculated and results are given for distributions of stream function, velocity, vorticity, turbulent kinetic energy and turbulent dissipation rate.更多还原
