“…Recently, temperature dependent thermal conductivity for fluid flow has been investigated in 15 and 16 . The heat and mass transfer for second grade fluid flow and micropolar hybrid nanofluid flow over stretching sheet in magnetic field was analysed by Awan et al 17 and Ai-Hanava et al 18 . Mabood et al 19 explored this idea to investigate the impact of thermal radiation on MHD Casson fluid flow in the presence of porous materials over a moving sheet.…”

Numerical analysis is performed for magnetohydrodynamics (MHD) couple stress nanofluid flow over a stretching sheet with melting and nonlinear radiation. The second law of thermodynamics is also incorporated with first-order slip. Nanofluid characteristics for thermophoresis and Brownian moments are encountered. The system that comprises differential equations of partial derivatives is remodeled into the system of differential equations via similarity transformations and then solved numerically through the Runge–Kutta–Fehlberg fourth-fifth (RKF-45) order technique. The physical parameters, which emerges from the derived system are discussed in graphical format. The significant outcomes of the current investigation are that the velocity field decays for a higher magnetic parameter. Another, important outcome of the study is both temperature and concentration are increasing functions of the first-order slip. Nusselt and Sherwood numbers are decreasing with an increase in magnetic strength. Further, Bejan number augment due to enhancement in the first-order slip and couple stress fluid parameters whereas a differing tendency is shown for magnetic and radiation parameters.

“…The latest investigation about temperature dependent thermal conductivity and hyperbolic annular fin with the technique of the step third derivative block method was done by Adeyeye et al 34 Ullah et al 35 showed the impact of Fourier's heat flux and gravity induced over a heated sensitive surface. Several examinations like thermal analysis of a Casson micropolar nanofluid, effect of lower and higher shear rates of viscosities on the transportation of heat/mass, electromagnetohydrodynamic flow through corrugated walls with variable viscosity, mixed convection with time‐dependent stagnation point flow of a Maxwell fluid and magnetohydrodynamics (MHD) oblique stagnation point flow of a second grade fluid over an oscillatory stretching surface were done by several investigators 36‐42 . Shehzad et al 43 published his latest study to investigate about behavior of nanoparticles Fe 2 SO 4 and Ti 6 Al 4 v in a micropolar fluid.…”

With respect to bionomical concerns and energy security, the performance of refrigeration systems should be enriched, which can be done by improving the characteristics of working liquids. Nanoliquids have attracted interest in the fields of engineering and industry due to their prominent thermophysical characteristics. Researchers have used nanoliquids as working liquids and noticed significant fluctuations in thermal execution. In this study, our prime aim was to study the impact of thermal radiation and varying thermal conductivity on a cross‐nanofuid with the addition of a nonuniform heat sink–source, chemical process, and activation energy (AE) together with effects of assisting and opposing buoyancy. Furthermore, the relationship of zero‐mass flux together with the mechanism of thermophoresis and Brownian motion is considered. Traditionalistic transformations gave the ordinary differential equations (ODEs), which are further dealt with the approach of the Shooting Scheme to change the boundary value problem (BVP) into an initial value problem (IVP) and a numerical comparison is made with the Matlab solver package bvp4c. Bvp4c is based upon a collocation scheme, which yields numeric outcomes for nonlinear ODEs with IVP. Impacts of the involved parameters on mass transfer profile, heat, and momentum fields are shown through graphs. Mass transfer of the cross nanofluid increases with increasing values of AE parameter. Values of physical quantities like drag forces, rate of transport of heat and mass in the case of assisting/opposing flow are tabulated. The drag force magnitudes are greater for enhancing values of M, a, and n, while on the other hand, the opposing tendency is seen for We1 and We2. The magnitude of the rate of heat transport (Nusselt number) falls for greater values of m, σ, δ, and Nt, but in contrast, it accelerates for E, Pr, and n.

The current investigation communicates the characteristics of upper-convected second grade nanofluid thin film flow over a time-dependent stretching sheet with variable thermal conductivity and Cattaneo-Christov double diffusion theory. The mathematical model generates a system of nonlinear partial differential equations (PDEs) for heat, momentum, and mass transfer phenomena. Similarity variables converted the PDEs into nonlinear ordinary differential equations (ODEs). Furthermore, received ODEs are numerically rescued with the built-in program Bvp4c in MATLAB. The impact of physical parameters like second-grade fluid λ, unsteadiness parameter S, Prandtl number Pr, Schmidt number Sc, variable thermal conductivity ε, variable diffusivity ε 1 , the square of dimensionless film thickness γ, relaxation time δ e , and retardation time δ c are scrutinized. Tables revealed numerical exposure and graphs depict the geometrical aspect of the current study. The velocity field is improved by heightening the λ, magnification in temperature is found for greater conductivity parameter ε. Greater δ e in the temperature profile goes smaller. The rate of mass transfer diminishes by uplifting the estimations in relaxation time parameter δ . c
