Variable fluid properties analysis with water based CNT nanofluid over a sensor sheet: Numerical solution

Present study is dedicated to analyze the magnetohydrodynamics (MHD) squeezed flow of nanofluid over a sensor shell under the influence temperature dependent viscosity. This is the first article on the squeezed flow of water based CNTs over a sensor surface with variable viscosity. A well known Reynolds model of viscosity is used. Modeling of the problem is based on the geometry and the interaction of nanoparticles namely single wall and multi-wall carbon nanotubes with the consistent 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. It is seen that when we increase Hartmann number M. viscosity parameter a and random constant b decreases temperature profile and thermal boundary layer thickness also decreases and increasing permeable velocity parameter f(0) increases temperature profile and thermal boundary layer thickness also increases.
