Abstract
The work reported in this thesis investigates analytically the hydrodynamic and thermal behaviour of fluid: for a fully developed natural convection flow in a vertical micro-porous-annulus (MPA), taking into account the velocity slip and temperature jump at the outer surface of the inner porous cylinder and inner surface of outer porous cylinder. A closed – form solution is presented for velocity, temperature, volume flow rate, skin-friction and rate of heat transfer expressed as a Nusselt number. The effect of various flow parameters on hydrodynamic and thermal behaviour such as suction/injection parameter, rarefaction parameter, fluid – wall interaction parameter and radius ratio are discussed with the aid of graphs. During the course of investigation, it is found that as suction/injection on the cylinder walls increases, the fluid velocity and temperature is enhanced. In addition, it is observed that wall surface curvature has a significant effect on flow and thermal characteristics, and also the effect of the velocity slip and temperature jump at the inner moving porous cylinder wall is much greater than its effects at the outer stationary one.
