The Effect Of Non – Dimensional Parameter(NE)On The Velocity And Temperature For The Non- Newtonian Fluids During Its Flow Through Inside Square Enclosure

Abstract

In this research the effect of non – dimensional parameter (NE) of Prandtl – Eyring model on the velocity and temperature for the inside square enclosure has been studied . The research used a numerical study for steady natural heat induction with some conditional , these are the perpendicular walls were heated in a different regular heat and the horizontal walls were isolated . The finite difference method was used to solve the formulas related to the inside square enclosure by using visual basic program . The results showed that the increase in the non-dimensional parameter(NE) increased the velocity and temperature , Also the increase in NE increased the value of flow ψmax until the maximum value was reached at (25.32) for the modified Rayleigh number of (110000) .The same results appeared with the average Nusselt number until it reaches its high value (11.42) at modified Rayleigh number of (110000) and NE =10 . All trials were performed at modified Prandtl number (Pr*=15) .
