The present article reports the combined effects of radiation and heat origination on the electro-kinetically induced hydromagnetic squeezed flow of a pseudoplastic fluid. The fluid is passing over a microcantilever sensor surface positioned in the superficial free stream. Microcantiliver sensor can detect the flow rate and the variance in the temperature of the fluid. The thermal conductivity and fluid viscosity are assumed as a function of temperature. Boundary layer approximations are considered to construct a pseudoplastic fluid flow model. The governing system is then resolved into a non-dimensional form with the assistance of an appropriate set of control parameters. The solution to these non-dimensional equations has calculated with the assistance of familiar numerical techniques i.e. Shooting technique. The results specify that flow of fluid, temperature, and velocity profiles are remarkably influenced by the radiation parameter, fluid parameter, heat generation parameter, thermal relaxation parameter, magnetic parameter, and the squeezing number. A comprehensive graphical and tabular study is constructed to check the convergence of the obtained results. One can detect that the temperature curve is changing slightly for the Christov-Cattaneo heat transfer model as compared to classical Fourier's law of heat transfer. Further, the physical quantities, i.e. free stream velocity, variable viscosity, thermal conductivity, Weissenberg number, and Prandtl number have strong impacts on the boundary layer flow equations. It is perceived that the fluid velocity profile rises for the growing value of the magnetic parameter, but reduces for squashed flow index b. Also, a positive variation is found in the temperature profile for rising values of and .

“…Khan et al discussed the Entropy generation minimization and heat transport in the radiative flow of nanomaterials over a thin moving needle. Khan et al presented the numerical study on vortex‐induced by an elastic rigid cylinder in cross‐flow direction for a range of reduced velocity, which corresponds to Reynolds number, mass‐ratio, and mass‐damping ratio. Hayat et al analyzed the simultaneous impact of Joule heating and viscous dissipation in the radiative flow of viscous fluid by a stretching cylinder.…”

Boundary layer flow phenomenons on a stretching sheet find numerous applications in industrial processes such as manufacture and extraction of rubber and polymer sheets. The current study focuses on two‐dimensional water boundary layer flow on exponential stretching surface with a vertical plate for variable physical properties of fluid such as viscosity and Prandtl number. The Quasilinearization technique has been used on governing equations to transform nonlinear to linear equations and these equations are discretized by finite difference techniques to get numerical solutions. The effect of buoyancy parameters (λ), velocity ratio parameter (ε) and streamwise coordinator (ξ) on velocity profiles (F), temperature profiles (θ), local skin‐friction coefficient (Cfx(ReLξexp(ξ))1/2) and the local Nusselt number (Nux(ReLξexp(ξ))−1/2) has been analyzed graphically based on numerical outcome. The magnitude of velocity profiles true(Ftrue) increases and temperature profile decreases approximately by 4% and 16% with increases the buoyancy parameter from λ = 1 to λ = 3 at = 0.5 and ξ = 1.0. The skinfriction and heat transfer coefficient increases approximately by 22% and 27% with an increase in ξ from 0.5 to 1.0 at fixed ε = 0.5 and λ = 1.0. The variations of velocity profiles and temperature profiles have more impact with εas compared to ξ and λ. The benchmark studies were carried out to validate the current results with previously published work and found to be in excellent agreement.

Original scientific paper https://doi.org/10.2298/TSCI171126140KHere an analysis is presented to investigate the characteristics of non-Fourier flux concept in flow induced by stretching cylinder. Unlike the convectional approach, the heat flux by Cattaneo-Christov theory is considered. Stagnation point flow in the presence of thermal stratification and temperature dependent thermal conductivity is addressed. Rheological properties are examined for hyperbolic tangent material. Theory of the boundary-layer is implemented for the formulation purpose. The relevant transformations yield the strong non-linear differential systems which are numerically computed. Plots are presented for the solution expressions of velocity and temperature. Surface drag force is calculated and discussed. Here velocity and temperature are enhanced for the larger curvature parameter. Larger values of thermal relaxation factor give rise to be decrease in temperature.
