Influence of wall slip and jump in wall temperature on transport of heat energy in hybrid nanofluid

It is the first time that partial slip and jump in wall temperature during transfer of thermal energy in hybrid nanofluid are considered simultaneously. Modeling of a considered phenomenon is done, and numerical treatment is done by FEM in order to analyze the impact of partial slip and jump in wall temperature on the transport of energy. It is observed that wall momentum diffuses into nanofluid faster than its diffusion in hybrid nanofluid in the presence of partial slip. Thermal performance of hybrid mononanofluid is greater than that of nanofluid. It is also noted that hybrid nanofluid exerts less shear stress than the shear stress that of mononanofluid. Hence, the use of hybrid nanofluid is beneficial in two ways (1) its thermal performance is higher than the base fluid or nanofluid and (2) the hybrid nanofluid exerts less shear stress on the wall. Therefore, the use of hybrid particles is recommended to optimize the thermal performance of the working fluid.
