Simulation of the Forced Convection Heat Transfer Non- Newtonian Nanofluid, Aqueous Solution of Carboxymethyl Cellulose- Aluminum Oxide, in Slip Flow Regime Through a Microtube

In the present study the flow and heat transfer of Non- Newtonian nanofluid, aqueous solution of carboxymethyl fractions of nano particles in a two dimensional microtube is simulated for the first time. Slip velocity and temperature jump boundary conditions are also considered along the microtube walls. The accuracy of the results obtained is investigated by comparison with those of previous data. The results are presented as isothermal contours, Nusselt number and the profiles of temperature and velocity at different cross sections of the microtube. It is observed that Nusselt number ncreases with slip velocity coefficient and volume fraction of nano particles; while its rate is more sensitive at higher values of Reynolds number.
