ABSTRACT
An attempt has been made to analyze the impact of dissipation and activation energy on convection heat transfer flow of a nanofluid in vertical channel. Brownian motion of thermophoresis in the presence of heat sources. By employing Runge-Kutta shooting technique the non linear governing equations have been solved. The velocity, the temperature and nano particle concentration have been discussion for different parametric variation. It is found that an increase is Eckert number (Ec) increase in velocity and temperature smaller Concentration. Cf, Sh grow, Nu decay with Sc. Cf, Nu grow with Ec at.? ? ?1. Temperature and nanoparticle concentration grow and velocity augments with increase in E1.Increase in ? grows the velocity, temperature and reduces nanoparticle concentration.
