Critical Layers m Parallel Flows

Finite amplitude neutrally stable two-dimensional disturbances in parallel flows are determined for large Reynolds numbers when both nonlinearity and viscosity are important in the critical layer. The phase shift across the critical laye...

Effects of Critical Layer Structure on the Nonlinear Evolution of Waves in Free Shear Layers

A theoretical study is made of the nonlinear development of a slowly modulated wavetrain of the symmetric neutral mode of a tanh y shear layer. The shear l...

The evolution of the critical layer of a Rossby wave

The evolution of a Rossby wave forced on a uniform shear is considered, the strength of the wave being characterised by a parameter ∊ ≪ 1. In the fir...

Absolute rate constants for the reactions of O(3P) atoms with DCl and DBr

Earlier work on the reactions of O( 3 P) atoms with HCl and HBr has been extended by measuring rate constants for A flow-tube method was used with chemiluminescent monitoring of the removal of atomic oxygen. Rate constants were measured ...
