Amplification of Heat Transfer in Three Immiscible Fluids: Micropolar Nanofluid Encased with Porous Matrix

Abstract

An investigation of the micropolar nanofluid sandwiched between permeable fluids enclosed in a horizontal channel is illustrated. The flow is modeled using Tiwari-Das single phase model to interpret the nanofluid and Brinkman model to define the permeable fluid. Closed form solutions are accomplished in the three regions utilizing the boundary and interface conditions. Graphical results are sketched for the reaction of material parameter, solid volume fraction, porous parameter, Eckert number, nanoparticles and cell rotational viscosity for the linear velocity, microrotation velocity and temperature. The skin friction, Nusselt number and mass flow rate are also reckoned. Velocity and temperature are down toned with material parameter, solid volume fraction and porous parameter whereas Eckert number develops the temperature. The optimal Nusselt values are obtained for Graphite oxide when compared with copper, silver and copper oxide nanoparticles.
