We develop a geometric formulation of fluid dynamics, valid on arbitrary Riemannian manifolds, that regards the momentum-flux and stress tensors as 1-form-valued 2-forms, and their divergence as a covariant exterior derivative. We review the necessary tools of differential geometry and obtain the ...
The amount of momentum flux induced by breaking waves is thought to contribute significantly to air-sea exchanges in high wind conditions. Recent models of these transfers incorporate parameterizations based on the breaker length, speed and the amount of coverage of breaking waves. To provide guidance...
For the logarithmic region, both the inactiveand active components of MF and HF are found to contribute to their mean flux. In theouter region, the ejections of HF are remarkably stronger than those of the MF, and theformer is more sparse in the physical space. Reynolds number is shown ...
Integrals under the momentum flux spectra are compared in all runs with the predictions of the standard empirical formula, and in two cases are compared with the values of the total wind stress as measured with a sonic anemometer; ... Fred W. Dobson - 《Journal of Fluid Mechanics》 被引量...

The momentum in the horizontal direction inside the control volume at any time t is, with x˙ denoting dxl dt,mℓ(ℓ−x)x˙, and the net momentum outflux is [mℓx˙]x˙. Thus, if T denotes the tension at the corner point of the rope at time t, we have Sign in to ...
