Abstract

This work explores the three-dimensional laminar flow of an incompressible second-grade fluid between two parallel infinite plates. The assumed suction velocity comprises a basic steady dispersal with a superimposed weak transversally fluctuating distribution. Because of variation of suction velocity in transverse direction on the wall, the problem turns out to be three-dimensional. Analytic solutions for velocity field, pressure and skin friction are presented and effects of dimensionless parameters emerging in the model are discussed. It is observed that the non-Newtonian parameter plays dynamic part to rheostat the velocity component along main flow direction.

Highlights

  • In recent years the laminar flow control (LFC) problem has attained significant importance in the field of aeronautical engineering

  • Many researchers have explored fluid flow problems with suction; the majority of these investigations cope with two-dimensional flows only

  • Gersten and Gross [2] studied the impact of transverse sinusoidal suction velocity on viscous fluid flow with heat transfer over a porous plane wall

Summary

Introduction

In recent years the laminar flow control (LFC) problem has attained significant importance in the field of aeronautical engineering. Gersten and Gross [2] studied the impact of transverse sinusoidal suction velocity on viscous fluid flow with heat transfer over a porous plane wall. Three-dimensional viscous fluid flow through infinites parallel planes with injection/suction was studied by Chaudhary et al [4]. Workers [5] explored three-dimensional fluctuating flow of viscous fluid through two parallel infinite plates with heat transfer. Three-dimensional viscous fluid flow between two parallel infinite planes was deliberated with injection/suction by [6]. This study, three-dimensional flow of the second-grade fluid along plane tends to two-dimensional flow [2]; because of varying suction in the sinusoidal injection/suction is inspected. A constant injection or suction velocity at thevelocity plane tends to perpendicular direction plane, the problem becomes three-dimensional. 4 estimatesthe solutions, Section 5 includes the discussion, and Section 6 summarizes the conclusions
