Finiteamplitude highfrequency oscillations in a compressible laminar boundary layer
Abstract
The twodimensional unsteady laminar boundarylayer flow of a compressible fluid is examined in the vicinity of a stagnation point when the main stream fluctuates in amplitude about a steady mean. The analysis is restricted to high frequencies of oscillations but no linearization in amplitude is made. The basic equations and boundary conditions are written in two sets of dimensionless variables appropriate to the inner and outer regions of the boundary layer. Series solutions valid in the inner and outer regions are then obtained and arbitrary functions in these solutions are determined. It is noted that heat transfer has a dominant fluctuating part at high frequencies, unlike the corresponding situation for an incompressible fluid.
