Mixed convection of the hybrid nanofluid flow through the (BFS) backward facing step is investigated numerically. Rectangular duct exposed to uniform heat flux(2000 W/m^2) coming from the step’s downstream wall. the flow is laminar, two types of nanofluid ZnO and TiO2 then the combined of them the hybrid nanofluid (TiO2-ZnO) is performed in various range of nanoparticle (0.5% to 3%), Reynolds number from (800 to 1200). Results clearly show a greatimprovement in transferring heat and friction factor.it has been indicated a significantlyincrease in theNusselt number and heat transfer coefficient with increasing Reynolds number as well as the volume fraction. But the friction factor is decrease with increasing the Reynolds number. it’s concluded that the hybrid nanofluid in enhancing the heat transfer approximately 14% through the backward facing step.
