建立在Rayleigh-Bénard流和Taylor-Couette流之间的定量类比的基础上，我们描述了角动量流以及湍流和层流耗散在横向运动方面的差异。在这个模型中推导出的扭矩与刘易斯和斯温尼的观测结果定量一致。该模型还预测了雷诺数和扭矩在不同的半径比之间的关系。
Building on a quantitative analogy between Rayleigh-Bénard flow and Taylor-Couette flow we describe the angular momentum current and the difference between turbulent and laminar dissipation in terms of the transverse motions. The torque derived within this model is in quantitative agreement with observations by Lewis and Swinney. The model also predicts relations between Reynolds number and torque at different radius ratios.
