Research in Inhomogeneous Turbulent Wake Flows. Part II. Elastic Jelly Model.

Abstract

The report deals with an inviscid stream flowing over an elastic jelly with an appropriate rigidity n. In response to the initial disturbances, the turbulent fluid develops Reynolds stresses which persist after an element of fluid passes into a different environment. Development of a dispersion relation examines the response of the turbulent fluid to small perturbations of the boundary, assuming that the turbulent fluid behaves like an elastic jelly, and examines the response spectrum. The external parameter is the stiffness number which is based on the fluid velocity and elastic rigidity of the medium.
