Effect of viscosity on internal waves from a source in a wall
Abstract
The solution for a line source of oscillatory strength kept at the origin in a wall bounding a semi-infinite viscous incompressible stratified fluid is presented in an integral form. The behavior of the flow at far field and near field is studied by an asymptotic expansion procedure. The streamlines for different parameters are drawn and discussed. The real characteristic straight lines present in the inviscid problem are modified by the viscosity and the solutions obtained are valid even at the resonance frequency.
