NUMERICAL STUDY OF FORCED CONVECTION OF AIR IN A U-SHAPED CAVITY

In this work, we numerically study laminar flows in forced convection a U -shaped channel. Our was based on finite volume method by the fluent code carried out for Reynolds number varying range 100<Re<700, and Rayleigh Ra=105 Prandtl Pr=0.72. As function of number, results obtained are presented form thermal dynamic field, variation Nusselt speed average temperature at outlet channel as Re also. We see significant improvement heat exchange along all walls increases Re.
