Concentration profile mass transfer
WebThis work consists of a theoretical boundary layer analysis of heat and mass transport in a viscous fluid-embracing gyrotactic micro-organism over a cylinder. The flow governing … WebA mathematical model is developed for unsteady state situations using slip conditions. Analytical expressions for the velocity, temperature and concentration profiles, wall shear stress, rates of heat and mass transfer and volumetric flow rate have been obtained and computationally discussed with respect to the non-dimensional parameters.
