INTEGRAL TRANSFORM METHODS SOLUTION OF BINGHAM FLUID FLOW

Abstract

abstract In this research We stu dy the Blngham fluid flow by the method of integral transforms which are considered as the most efficient methods for solving physical and engineering problems. Investigation of flow characteristics of Bingham fluid and the differences between a Newtonian and non-Newtonian fluid Was given. The basic equations that describing shear stress and velocities of non-Newtonian fluids were discussed. Finally We applied the Laplace and Fourier transforms for solving a problem of unsteady state unidirectional flow of Bingham fluid and we found that the integral transform methods is suitable for problems of this kind.
