采用正交曲线坐标系下曲率修正的紊流数学模型 ,计算了龙抬头泄洪洞明流流动的水力要素 .计算结果表明 :具有明显曲率影响的泄水建筑物反弧水流的数值计算 ,必须计入流线弯曲的影响 ;本文建立的曲率修正紊流数学模型能够较好地预测具有明显曲率影响的复杂水流的水力特性 .
The turbulence mathematical model of curvature correction in orthogonal curvilinear coordinate system is used to calculate the hydraulic factor of the Mingliu flow in the Longtountou spillway tunnel.The calculation results show that the numerical calculation of the reverse arc water flow of the draining structure with the obvious curvature must be calculated Inflow curve bending effect. The turbulence-corrected turbulence mathematical model established in this paper can predict well the hydraulic characteristics of complex flow with obvious curvature.
