FORMULATION OF STABILITY OF PLANE POISEUILLE FLOW WITH TEMPERATURE-DEPENDENT VARIABLE VISCOSITY,

Abstract

The present investigation is a preliminary effort toward understanding the effect of temperature-dependent variable viscosity on hydrodynamic stability. The flow pattern chosen in this work is plane Poiseuille flow which predicts no inviscid instability for constant viscosity. By taking into account the variation of viscosity, it is found that the velocity profile of the basic flow possess a vorticity maximum. This might suggest instability for large Reynolds number. The stability equations and the boundary conditions are derived to compare with those of constant viscosity. (Author)
