SiO2-Al2O3/water hybrid nanofluid flow near stagnation-point on a vertical permeable flat plate

Hybrid nanofluids are potential fluids that offer better heat transfer performance and therrnophysical properties than convectional heat transfer fluids (oil, water andethylene glycol) and nanofluids with single nanoparticles. Here, a kind of hybrid nanofluid including silicon dioxide and aluminium oxide nano-size particles with water asbase fluid is analytically modeled to develop the problem of the steady laminar MHD mixed convection boundary layer flow of a sioz _Al._,O3/water hybrid nanofluid nearthe stagnation point on a vertical permeable flat plate. In first, analytic modeling of hybrid nanofluid is presented and using appropriate similarity variables, the governingPDES are transformed into nonlinear ODEs i11 the dimensionless stream function, which is solved numerically applying the function bvp4c from MATLAB. Our results demonstrate that the developed model can be used with great confidence to study the flow and heat transfer of hybrid nanofluids.
