Second law analysis of heat transfer in swirling flow of Bingham fluid by a rotating disk subjected to suction effect

This framework presents heat transfer analysis for swirling flow of viscoplastic fluid bounded by a permeable rotating disk. Problem formulation is made through constitutive relations Bingham model. Viscous dissipation effects are pre-served in the mathematical Entropy production which yet to be explored von-Karman non-Newtonian fluids. Having found similarity equations, these have been dealt numerically broad parameter values. The solutions remarkably influenced wall suction and number measures yield stress. Akin earlier numerical results, thermal boundary-layer suppresses upon increasing velocity. Thermal penetration depth much enhanced when stress becomes large. Higher rate can accomplished employing higher velocity at However, deterioration anticipated as enlarges. Current results perfect line with those an existing article limiting sense.
