Abstract:

In this paper, we investigate the variation of concentration of urea in a viscous, incompressible, laminar and Newtonian fluid that flows in a divergent/convergent tube of slightly varying non-uniform cross-section with semi-permeable wall. The concentration in the fluid is considered as a function of both axial and radial distances. The governing diffusion equation is solved analytically. The effects of slope parameter k, amplitude ratio (ratio of amplitude to the inlet width) and Sherwood number on the concentration of urea in the blood are presented graphically. The results shows that the variation of slope parameter, amplitude ratio and Sherwood number have considerable influences on the concentration level in such a fluid flow.
