Heat transport investigation of magneto-hydrodynamics (SWCNT-MWCNT) hybrid nanofluid under the thermal radiation regime

The prime objective of the present study is to examine the comparison of heat transfer attributes of magnetohydrodynamic hybrid nanofluid flow in the presence of radiation. The phenomenon of generally new standard fluid “hybrid nanofluid”, has been explored to enhance the heat coefficient in the boundary layer flow. Single wall and Multiwall carbon nanotube particles (nanometer in size) have been utilized to constitute the required hybrid nanofluid. The nonlinear system of differential equations is handled through the bvp4c MATLAB algorithm. The Nusselt number increases significantly for lower values of pressure and decreases for higher pressure gradients while keeping the radiation value at zero. The Sherwood number first increases for lower buoyancy parameters and then decreases for higher values, for both hybrid nanofluid cases. The local skin friction decreases for minimum rotation then it increases for higher rotation in both directions, it shows similar behavior for both cases. These hybrid nanofluids can enhance the performance of heat exchangers, electronic cooling, heating in pipes, car radiators, nuclear plants, solar heating. The study suggests exploitation of these fluids can be helpful to reduce the production cost.
