Heat transfer and entropy analysis in squeezing flow of hybrid nanofluid (Au-CuO/NaAlg) with D-F (Darcy-Forchheimer) and C-C (Cattaneo-Christov) heat flux

Hybrid nanofluid bounded between two infinite parallel surfaces in presence of D-F (Darcy-Forchheimer) porous medium is explored in this analysis. Heat transport is explored by C-C (Cattaneo-Christov) heat flux and thermal radiation. Flow is originated due to squeezing of upper and stretching infinite surfaces. Entropy and Bejan number are part of this study. Lower surface is subject to convective boundary condition. Mathematical modeling of flow field is done under aforementioned assumptions. By transformation technique, PDEs (flow and heat transport expressions) are changed into ODEs. Solutions are obtained via ND-solve (shooting technique). Quantities of our interests (flow, entropy, velocity, Bejan number, skin friction) are evaluated under involved variables. Velocity of both hybrid nanomaterial and nanofluid boosts against higher squeezing and porosity parameters and Forchheimer number. Dominated behavior of velocity in case of hybrid nanomaterial is observed when compared with nanofluid. Fluid temperature intensifies by squeezing parameter and Eckert number while reduction occurs for radiation parameter. Variation in temperature is more for hybrid nanomaterial. Entropy production rate reduces for higher squeezing parameter while it increases through porosity parameter. Bejan number is an increasing function of squeezing parameter while it reduced for porosity parameter. Skin friction is controlled by squeezing parameter and Forchheimer number.
