EFFECTS OF VISCOUS DISSIPATION AND HEAT GENERATION/ABSORPTION ON NANOFLUID FLOW OVER AN UNSTEADY STRETCHING SURFACE WITH THERMAL RADIATION AND THERMOPHORESIS

摘要

Heat and mass transfer that exerts its influence on nanofluid flow through a heated stretching sheet with thermal radiation, viscous dissipation, and heat generation/absorption is analyzed. The transport model is influenced by Brownian motion and thermophoresis. The governing nonlinear PDEs are converted into a system of nonlinear ODEs by means of supplementary transformations and then handled numerically from the assisting RKF scheme of the 45th order with shooting procedure. The thermal field and concentration field are presented graphically for values of heat generation/absorption parameter, thermal radiation parameter, thermophoresis parameter, and Eckert number. The Nusselt number and Sherwood number are tabulated. The results of this study show that the heat transfer coefficient decreases with increase in the heat generation/absorption parameter and Eckert number, while the reverse trend is observed for mass transfer rate for the same pertinent parameters.
