Turbulence and Mixing in Holmboe Waves

0097124 -- Smyth/OSU该项目是一个初步的数值研究，研究Holmboe波是否能在理想化的分层流配置中产生明显的混合，类似于在某些海洋状态（如交换流）中可能预期的混合。 本研究将检验是否可以实现显著的混合效率。 一个连续分层流的谱模式包含一个尖锐的密度梯度和一个更温和的剪切梯度将被用来进行直接的数值模拟的增长和非线性发展的Holmboe波。如果数值结果提供证据，Holmboe不稳定性导致有效的混合，这将提供一个动力，更彻底的研究的生命周期的Holmboe不稳定性和相关的混合。

0097124 -- Smyth/OSUThis project is a preliminary numerical investigation of whether Holmboe waves can generate appreciable mixing in idealized stratified flow configurations similar to those that might be expected in some oceanic regimes such as exchange flows. This research will examine whether a significant mixing efficiency can be achieved. A spectral model of acontinuously stratified flow containing a sharp density gradient and a more gentle shear gradient will be used to make direct numericalsimulations of the growth and nonlinear development of Holmboe waves.If numerical results provide evidence that the Holmboe instability leadsto effective mixing, this will provide an impetus for a more thorough investigation of the life-cycle of Holmboe instabilities and the associated mixing.
