Influence of heat generation/absorption and stagnation point on polystyrene–TiO2/H2O hybrid nanofluid flow

Abstract

This article focuses on hybrid nanofluid flow induced by stretched surface. The present context covers stagnation point flow of a hybrid nanofluid with the effect of heat generation/absorption. Currently most famous class of nanofluids is Hybrid nanofluid. It contains polystyrene and titanium oxide as a nanoparticles and water as a base fluid. First time attributes of heat transfer are evaluated by utilizing polystyrene–TiO2/H2O hybrid nanofluid with heat generation/absorption. Partial differential equations are converted into ordinary differential equation by using appropriate transformations for heat and velocity. Homotopy analysis method is operated for solution of ordinary differential equations. Flow and heat are disclosed graphically for unlike parameters. Resistive force and heat transfer rate is deliberated mathematically and graphically. It is deduced that velocity field enhanced for velocity ratio parameter whereas temperature field grows for heat generation/absorption coefficient. To judge the production of any engineering system entropy generation is also calculated. It is noticed that entropy generation grows for Prandtl number and Eckert number while it shows opposite behavior for temperature difference parameter.

Numerical Study on the Influence of heat generation and absorption on an incompressible hybrid nanofluid's magnetohydrodynamic (MHD) flow in a thermal system

“…Masood et al [34] discussed about the characteristics of heat generation/absorption over the polystyrene (TiO2/H2O) hybrid nanofluid flow. In their work they found out about the extraordinary enhancement in thermal conductivity of the hybrid nanofluids as compared to just ordinary nanofluids and hence concluded that they partake immeasurable uses in engineering, paints, home, industry, food colorants, ceramics, pharmaceuticals, paper production, in cancer treatment, fabrics, cosmetics, soaps, automotive industry as well as food packaging.…”

Effect of inclined magnetic field on radiative heat and mass transfer in chemically reactive hybrid nanofluid flow due to dual stretching

“…They remarked that the electric field directly influences the temperature profile. In recent years, Hassan 20 , Hussain 21 , Sheikholeslami 22 , Masood and Farooq 23 and Masood 24 have explored hybrid nanofluid in the presence of different body forces.…”

Nonsimilar modeling analysis of Carreau–Yasuda mixed convective flow in a porous medium subjected to Soret and Dufour influences

“…Different physical phenomenon, ranging from gravitation system to fluid dynamics, are governed by nonlinear partial differential systems (PDEs) and it is difficult to obtain their solutions. Although, similarity technique has been extensively employed in literature [40][41][42][43][44][45][46] to transform the nonlinear PDEs into ODEs, but the technique cannot be used to a significant extent because of some of its limitations. To tackle nonsimilar problems Sparrow and Yu [47] presented the technique of local nonsimialrity.…”
