Assesment of Thermodynamic Irreversibility in a Micro-Scale Viscous Dissipative Circular Couette Flow
We investigate the effect of viscous dissipation on the thermal transport characteristics of heat and its consequence in terms of the entropy-generation rate in a circular Couette flow. We consider the flow of a Newtonian fluid through a narrow annular space between two asymmetrically-heated concentric micro-cylinders where the inner cylinder is rotating at a constant speed. Employing an analyt...
متن کاملTransition in circular Couette flow
Two distinct kinds of transition have been identified in Couette flow between concentric rotating cylinders. The first, which will be called transition by spectral evolution, is characteristic of the motion when the inner cylinder has a larger angular velocity than the outer one. As the speed increases, a succession of secondary modes is excited; the first is the Taylor motion (periodic in the ...
متن کاملLinear stability of viscous supersonic plane Couette flow
The linear stability of viscous compressible plane Couette flow is not well understood even though the stability of incompressible Couette flow has been studied extensively and has been shown to be stable to linear disturbances. In this paper, the viscous linear stability of supersonic Couette flow for a perfect gas governed by Sutherland viscosity law was studied using two global methods to so...
متن کاملAnalysis of Inherent Irreversibility in a Variable Viscosity MHD Generalized Couette Flow with Permeable Walls*
The inherent irreversibility in a variable viscosity hydromagnetic generalized Couette flow with suction/injection at the walls has been investigated theoretically. Using a fourth-order Runge-Kutta-Fehlberg integration scheme together with shooting technique, the model equations for momentum and energy balance are tackled numerically. The velocity and the temperature profiles are obtained and a...
متن کاملInstability criterion for oblique modes in stratified circular Couette flow
An analytical approach is carried out that provides an inviscid stability criterion for the strato-rotational instability (in short SRI) occurring in a Taylor-Couette system. The control parameters of the problem are the rotation ratio μ and the radius ratio η. The study is motivated by recent experimental [1] and numerical [2, 3] results reporting the existence of unstable modes beyond the Ray...
