Numerical study of mixed convection in a microchannel using Al۲O۳ hybrid nanofluid

By developing the high-tech instruments especially in digital devices, a need to have an efficient and compact cooling is of crucial importance. In the current study, heat transfer enhancement in a microchannel for cooling two hot sources is numerically investigated. The effects of imposing a magnetic field, a pulsating flow, and using a hybrid nanofluid are tested. Further, the entropy generation is evaluated and the strength of irreversibility sources is discussed. Reynolds number, Hartmann number, nanofluid volume fraction, inlet velocity amplitude, and frequency are chosen as the independent parameters.
