Abstract
This paper deals with the fully developed mixed convection flow of a viscoelastic fluid between permeable parallel vertical walls. The equations are modelled using the fully developed flow conditions. An exact solution is obtained for the fluid velocity and temperature distributions. The results are graphically displayed and the influence of the viscoelastic parameter K, Reynolds number Re, Grashof number Gr, cross-flow parameter R and Prandtl number Pr is discussed.
