AI 中文摘要
我们发展了一种理论,用以确定在湍流快速旋转流体中形成的相干地转涡旋的平均速度径向分布。根据我们的实验条件,我们假设涡旋中的流动由来自涡旋外围的短波长惯性波的吸收所维持。在该理论中,波之间的非线性相互作用被假定为可忽略。与实验数据的比较支持了所发展模型的有效性。
英文摘要
We develop a theory that determines the radial profile of the mean velocity in a coherent geostrophic vortex forming in a turbulent rapidly rotating fluid. Following the conditions of our experiments, we assume that the flow in the vortex is sustained by the absorption of short-wavelength inertial waves arriving from the vortex periphery. The nonlinear interaction between waves is assumed negligible in the theory. Comparison with experimental data supports the validity of the developed model.
