The interaction of a two-dimensional jet with three-dimensional perturbations
Abstract
The paper examines the crossing-type interaction of three-dimensional perturbations in the form of finite-amplitude oblique Tollmein-Schlichting waves with a two-dimensional laminar jet which is not confined by solid boundaries. The analysis, based on the solution of the Reynolds equations, leads to the determination of the form of the longitudinal vortex induced by the perturbations; and the distortion of the mean-flow profile is determined for various Reynolds numbers and perturbation intensities. The stability of the resulting flow is investigated, and it is shown that the secondary flow is more stable than the initial one.
