Gravity Wave Instability and Turbulence

摘要: Abstract Gravity waves and flow instability often exist simultaneously. It has been suggested that turbulence in a stably-stratified fluid is due to wave instability, it speculated can generate gravity waves. In some cases, exchange kinetic energy. Chapter 5, we explore the various modes of instability. We begin with simple examination stability terms work done on or by system. A natural extension this analysis leads Kelvin–Helmholtz interface between two semi-infinite fluids. When replaced shear layer, problem becomes more complicated, instabilities occur form modes. mechanical process leading actions mean described modulated Richardson number. theoretical energy discussed coupling processes. The chapter concludes first-order analyses wave-modified surface drag Jefferys’ roll-wave
