本文力图将熟知的湍流大涡运动现象与湍流模型理论联系起来以减少模型理论中的经验关系。 在剪切流中以球的流体动力系数,分析确定了涡球的运动,并以此确定剪切流中的湍流剪应力。由此得到了一个二方程模型,方程中仅包含球的流体动力系数。 平板湍流边界层的实例计算表明,计算的速度剖面在整个边界层中都能很好地与实验符合。 This article seeks to reduce the empirical relationship in model theory by relating the well-known phenomenon of turbulent large-eddy motion to turbulence model theory. In the shear flow, the hydrodynamic coefficient of the ball is analyzed to determine the motion of the vortex ball and to determine the turbulent shear stress in the shear flow. Thus a two-equation model is obtained in which only the hydrodynamic coefficients of the ball are included in the equation. An example of a plate turbulent boundary layer shows that the calculated velocity profile fits well with the experiment in the entire boundary layer.
