The effect of Nusselt number on the bi-viscosity fluid subjected to the discrete heating effect

Discrete heating action has been established as an energy efficient method. Nusselt number plays a significant role in the heat transfer rate. Local is useful analyzing rate along sections of side walls with different or same temperature heated enclosed cavity. Whereas average quantifies total change closed While path trajectory flow being analyzed by function. In current work, multiple heaters length , and are assembled at each isosceles triangle. The numerical simulations modeled system boundary conditions carried out using standard Galerkin Finite Element Method. nonlinear algebraic solved Newton behavior fluid inside triangle observed. results reported terms graphs contours, streamlines, local numbers. maximum observed convection dominant case. By increasing magnitude bi-viscosity parameter, secondary circulation for direct relation parameter. values numbers achieved generation parameter against Grashof number.
