Abstract

which is independent of curvature effect. This also shows that the skin friction is neither affected by the elasticity of the liquid nor by the viscosity. Table 1 shows the effect of the elasticity of the fluid on the flowfield for different values of 77, R, and Rc*. When R is —2, the axial velocity is independent of the elasticity of the fluid. It is interesting to note that when R is greater than —2 (for example, —1), the velocity is damped, with the increase in elastic parameter, whereas, for values of R less than —2, the velocity increases with the elastic parameter. Being negative as R increases, the boundary-layer thickness decreases. These results agree with the corresponding results obtained by Mishra.
