Abstract:
The present study investigates the effects of shape factor nanoparticles on an oscillatory MHD flow of a nanofluid in two immiscible liquids in a horizontal porous channel with velocity and thermal slip on the walls. Thermal radiation, Joule heating, viscous and Darcy dissipations have been accounted for in the model. We have considered Al2O3 and Cu as nanoparticles, in the lower region (Region-I) and upper region (Region-II): respectively, with water as a base fluid. ; The effective ratio of thermal conductivity of the nanofluid is evaluated using the Maxwell-Garnetts model. The behavior of velocity, temperature, and rate of heat transfer distributions have been depicted graphically for the cases of slip and no-slip effects. This study has been made to understand the impact of different nanoparticle shape factors on temperature and the heat transfer rate. For various parameters, values of shear stress distribution at the walls and the mass flux are shown in a tabular form. ; Our study asserts that with the increase of the strength of the magnetic field, the velocity of the liquid falls and enhances the temperature of the liquid. The influence of different combinations of nanoparticles on the flow variables have also been discussed. In order to validate the analytical results, the numerical evaluation of the closed-form results for the velocity distribution has been compared with those of the numerical method, by using the NDSolve command in MATHEMATICA, and a good agreement is observed.
