EDDY FORMATION AND DECAY ON FREE STREAM BOUNDARIES.

Abstract

Equations are formulated for the growth of hydrodynamic disturbances in a jet stream. The non-linear interactions of finite amplitude disturbances are examined, using the NavierStokes equations. The jet stream is represented as a parallel shear flow, and the possible existence of a dominant disturbance mode is considered. A set of ordinary linear differential equations are developed to provide a method for the computation of the spatial growth of finite three-dimensional disturbances describing the characteristics of such possible dominant modes which might be pertinent to the stability, control, and structural response of missiles encountering atmospheric disturbances in jet streams.
