摘要
This work scrutinizes the hybrid nanofluids flow past a flat surface with radiation together with the subsistence of aligned magnetic field. Three distinct hybrid nanofluids such as aluminium oxide-silicon dioxide/water (Al2O3 - SiO2/H2O), aluminium oxide-titanium dioxide/water (Al2O3 - TiO2/H2O) and titanium dioxide-silicon dioxide/water (TiO2 - SiO2/H2O) are used in this study through Marangoni boundary condition. The partial differential equations controlling the heat transfer problem were upgraded to ordinary differential equations utilizing appropriate similarity transformation. Analytical result of the ordinary differential equations is achieved using Laplace technique. The precision of the analytical solution of flow function is validated by numerical solutions. The physical parameters achieve on the flow field and temperature field are brought about by graph and tables and are deliberated in detail. The important findings are the surface velocity and rate of heat transfer is little higher for Al2O3 - SiO2/H2O and TiO2 - SiO2/H2O respectively. The permeable parameter has a direct relation with flow field and indirect relation with temperature field.
