MHD squeezed flow of water functionalized metallic nanoparticles over a sensor surface

• Model consists of magnetohydrodynamics (MHD) flow of nanofluid with externally squeezed surface over a sensor surface.
• Three different kind of metallic nanoparticles are saturated within the base fluid.
• Numerical simulation is performed to analyze the fluid flow and heat transfer analysis.
• Water functionalized copper nanoparticle provide the better heat transfer as compare to the rest of mixtures.

Present study is devoted to analyze the magnetohydrodynamics (MHD) squeezed flow of nanofluid over a sensor surface. Modeling of the problem is based on the geometry and the interaction of three different kinds of metallic nanoparticles namely: copper (Cu), alumina (Al2O3) and titanium dioxide (TiO2) with the homogeneous mixture of base fluid (water). The self-similar numerical solutions are presented for the reduced form of the system of coupled ordinary differential equations. The effects of nanoparticles volume friction, permeable velocity and squeezing parameter for the flow and heat transfer within the boundary layer are presented through graphs. Comparison among the solvent are constructed for both skin friction and Nusselt number. Flow behavior of the working nanofluid according to the present geometry has analyzed through Stream lines. Conclusion is drawn on the basis of entire investigation and it is found that in squeezing flow phenomena Cu–water gives the better heat transfer performance as compare with the rest of mixtures.
