• VALIDITY OF THE UPPER BOUND FOR THE COMPLEX WAVE VELOCITY OF AN UNSTABLE PERTURBATION WAVE OF AN INVISCID HETEROGENEOUS SHEAR FLOWS
Abstract
The present paper concerns with the study of the validity of the upper bound for the complex wave velocity of an unstable perturbation wave of an inviscid heterogeneous parallel shear flows [1]. Graph are also plotted which shows the reduction of Howard’s [2] semi circle for the bound of the complex wave velocity
Keywords
Heterogeneous parallel shear flows, perturbation, linear stability, Howard’s semi circle.
