Abstract
This paper investigates heat transfer (HTR) and fluid flows of a magnetohydrodynamic (MHD) nanofluid (NFD) in a two-parallel-plate microchannel with three isothermal heat sources and under temperature jump and slip (0 < B* < 0.1) and non-slip regimes. The flow is subjected to a magnetic field (0 < Ha < 60) in three zones in the presence and absence of viscous dissipation (VDS) (0 < Br < 0.1). Using SIMPLE algorithm, it is found that a rise in the Re (0 < Re < 100) increases HTR under both slip and non-slip conditions. VDS decreases HTR from the isothermal heat source to the NFD flow. An increase in the slip coefficient raises the Nu, particularly at higher Ha. A rise in the Ha leads to greater HTR under the slip boundary condition. An increase in the slip coefficient raises the Nu by 52.52% in the presence of VDS and by 1.16% in the absence of VDS.
