“…As emphasized in the analysis [6] and [7] the selection of nanoliquid for engineering demands relies on their thermo-physical characteristics. Some attempts covering the aspect of heat transfer improvement can be mentioned through the studies [8][9][10][11][12][13][14]. The nanoliquid flow and heat transport towards stretched/shrunk surface have engrossed the attention of several scientists due to their numerous demands in industrial manufacturing procedures for instance in transportation, nuclear reactors, power generation, biomedicine, industrial and food applications.…”

This article addresses unsteady stagnation point flow of Oldroyd-B nanofluid past an impermeable stretching sheet. Characteristics of heat transfer are described within the frame of heat generation/absorption and nonlinear radiative process. Intention in present analysis is to develop a model for nanomaterial containing Brownian motion and thermophoresis phenomena. The resulting nonlinear differential systems have been solved for the convergent homotopic solutions. Behavior of sundry variable for the velocity, temperature and concentration are addressed. Numerical values examined the local Nusselt number. It is revealed that velocity field enhances for dimensionless retardation time while reverse situation is observed regarding dimensionless relaxation time. Temperature and heat transfer rate are enhanced via larger nonlinear thermal radiation and temperature parameters. Moreover, behavior of Brownian motion and thermophoresis on the concentration field is quite reverse.

In this paper, we examined the numerical and perturbative analysis of non-Newtonian fluid towards non-axisymmetric Homann stagnation-point flow. The Maxwell fluid model is applied to investigate the behavior of viscoelastic fluid for this particular geometry. The influence of Maxwell parameter $${\beta }_{1}$$ β 1 and ratio $$\gamma$$ γ on different profiles are addressed in this analysis. The governed partial differential equations are reduced to ordinary differential equations with the help of similarity transformations. The numerical and perturbative outcomes of the resulting system of differential equations are obtained by applying the shooting technique. The solution is achieved for diverse values of relaxation time parameter $${\beta }_{1}$$ β 1 and ratio $$\gamma$$ γ . The wall shear stress is compared to their large-$$\gamma$$ γ asymptotic behaviors and displacement thicknesses are also presented. The numerical data for velocity profiles are obtained in terms of plots. It is predicted through analysis that a gradual increase in relaxation time raises wall skin friction components. On the other hand, velocity decreases which constitutes to reduce the reverse flow. Meanwhile, displacement thicknesses in $$x$$ x and $$y$$ y direction decreases. However, three-dimensional displacement thickness increases due to more viscoelastic material like Maxwell fluid than viscous fluid.

“…Viscoelastic fluid-flow past a saturated porous medium was analyzed by Delenda et al [27]. The researchers [28][29][30][31][32][33][34][35] analyzed the flow over various geometries (cone, plate and sheet) with various flow physical characteristics (non-uniform heat source or sink, nanoliquids, and magnetic field).…”

Heat and mass transfer in 3-D MHD Williamson-Casson fluids flow over a stretching surface with non-uniform heat source/sink

A mathematical model has been proposed for investigating the flow, heat, and mass transfer in Williamson and Casson fluid-flow over a stretching surface. For controlling the temperature and concentration fields we considered the space and temperature dependent heat source/sink and homogeneous-heterogeneous reactions, respectively. Numerical results are carried out for this study by using Runge-Kutta based shooting technique. The effects of governing parameters on the flow, heat and mass transfer are illustrated graphically. Also computed the skin-friction coefficients for axial and transverse directions along with the local Nusselt number. In most of the studies, homogeneous-heterogeneous profiles were reduced into a single concentration equation by assuming equal diffusion coefficients. For the physical relevance, without any assumptions we studied the individual behavior of the homogeneous-heterogeneous profiles. It is found that the rate of heat and mass transfer in Casson fluid is significantly large while equated with the heat and mass transfer rate of Williamson fluid.
