Shear Stress and Heat Transfer Studies of Visco-Elastic Fluid Flowing Between Two Parallel Plates

Abstract

 In this paper we have carried out the “Shear Stress and Heat Transfer Studies of Visco-Elastic Fluid Flowing between Two Parallel Plates”. In the proposed problem, upper plate moves with a constant velocity and lower one is at rest. Perturbation technique is used to find out the solution up to first order approximation. Effect of visco-elasticity and frequency of fluctuation on flow pattern is discussed. Velocity profiles and shear stresses at lower and upper plates are calculated. Variations of amplitude and phase angle with respect to frequency parameter are shown graphically. Heat transfer through lower and upper plates is discussed, also.
