Squeezing flow of Cu-TiO2/ H2Ohybrid nanofluid with activation energy and chemical reaction in a Darcy-Forchheimerporous medium

Abstract

This paper presents numerical simulations of an unsteady squeezed flow of water-based hybrid incompressible nanofluid containing titanium oxide () and copper (Cu) as nanosolid particles between two parallel disks embedded in a Darcy-Forchheimer porous medium in presence of thermal slip and velocity slip together with a homogenous chemical reaction. The prime focus of the present investigation is to explore the velocity distribution, heat and mass transfer of the flow under the mentioned geometrical configurations. The leading PDEs is reduced into similarity non-linear ODEs with the help of relevant similarity transformation and then solved by the 4th order R-K integration technique accompanied with the shooting procedure. After numerical designs, the impact of diverse related factors on flow characteristics of the stream has been demonstrated via proper charts and graphs and described the consequences with apposite perspective. Some of the notable conclusions of the present study is that fluid temperature increases with growing values of activation energy and thermal slip, whereas the fluid velocity decrease with developing values of the porosity parameter, inertial parameter and squeezing number. Also thickness of concentration boundary layer leads to decrease with an intensification of squeezing number and chemical reaction parameter.
