Abstract

EFFECT OF VARIABLE VISCOSITY, ACTIVATION ENERGY AND IRREGULAR HEAT SOURCES ON CONVECTIVE HEAT AND MASS TRANSFER FLOW OF NANOFLUID IN A CHANNEL WITH BROWNIAN MOTION AND THERMOPHORESIS

Dr. K. Satya Narayana and *Dr. G. N. Ramakrishna

ABSTRACT

In this analysis an attempt has been made to investigate the effect of Brownian motion and thermophoresis effect on convective heat and mass transfer flow of nanofluid in a vertical channel with variable viscosity and activation energy in the presence of non-uniform heat sources. The non linear coupled equations have been solved by Runge-Kutta Fehlberg method considering shooting techniques. It is found that an increase in viscosity parameter (B) enhances the velocity, temperature and reduces nanoparticle concentration velocity and temperature reduces with E1 and depreciates with ?. Nano concentration augments with E1 and decays with ?.
