Computational outline on heat transfer analysis and entropy generation in hydromagnetic squeezing slip flow of hybrid nanofluid

Purpose The current work investigates an unsteady squeezed flow of hybrid-nanofluid between two parallel plates in occurrence with a uniform transverse magnetic field. Water is used as base fluid mixed with Graphene Oxide (GO) and Copper (Cu) nanoparticles. The flow considered here is under slip boundary conditions. Design/methodology/approach The governing PDEs are transmuted into ODEs by applying an appropriate similarity transformation and then solved numerically using the 4th order R-K method with shooting technique. Graphical illustrations for velocity, temperature, entropy generation ( <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"><m:mrow><m:msub><m:mi>N</m:mi><m:mi>G</m:mi></m:msub></m:mrow></m:math> ), Bejan number ( <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"><m:mrow><m:mi>B</m:mi><m:mi>e</m:mi></m:mrow></m:math> ), streamline etc. are presented and discussed in detail from the physical point of view. The nature of the Nusselt number is also studied numerically through contour plots for different flow parameters. Findings There is no funding obtained for the research work. Social implications This kind of study may be used in various fields including polymer processing, lubrication apparatus, compression including hydrodynamical machines compression, food processing etc. Originality/value It is observed that very little investigation has yet been made about the movement of hybrid nanofluid between two analogous plates.
