In the current paper, we endeavour to execute a numerical analysis in connection with the boundary layer flow induced in a non-Newtonian liquid by a stretching sheet with heat and mass transfer. The effects of chemical reactions and local thermal non-equilibrium (LTNE) conditions are considered in the modelling. The LTNE model is based on energy equations, and provides unique heat transfer for both liquid phases. As a result, different temperature profiles for both the fluid and solid phases are used in this work. The model equation system is reduced by means of appropriate similarity transformations, which are then numerically solved by employing the classical Runge–Kutta (RK) scheme along with the shooting method. The resultant findings are graphed to show the effects of various physical factors on the involved distributions. Outcomes reveal that Jeffrey fluid shows improved velocity for lower values of porosity when compared to Oldroyd-B fluid. However, for higher values of porosity, the velocity of the Jeffery fluid declines faster than that of the Oldroyd-B fluid. Jeffery liquid shows improved fluid phase mass transfer, and decays more slowly than Oldroyd-B liquid for higher values of chemical reaction rate parameter.
There are several regularly reported applications for the dispersion of nanoparticles in a conventional fluid along a vertical wall in clinical medicine, architecture and agriculture fields. On the other hand, it still has not been reported the effect of electromagnetohydrodynamic convective flow of nanofluid through a radiating, moving Riga plate with heat absorption. As a result, this paper examines a water-based nanofluid comprising copper and aluminum oxide along a moving Riga plate, taking into cognizance [Formula: see text] (stationary Riga plate) [Formula: see text] (moving Riga plate). The Laplace transform technique is used to solve the ODEs obtained after employing the similarity variables on the governing equations. The effect of various variables on the shear stress coefficient, Nusselt number, velocity and temperature distribution is explored and graphically shown. Driven by the electromagnetic force effect, the increased modified Hartmann number and radiative impact increase copper nanofluid over aluminum oxide nanofluid on the moving plate. Simultaneously, heat absorption favors a modest decrease in aluminum oxide nanofluid’s thermal and velocity fields over copper nanofluid.
This paper explores the flow of dusty fluid over a stretching rotating disk with thermal radiation. Further, the convective boundary condition is considered in this modeling. The described governing equations are reduced to ordinary differential equations by using apt similarity transformations and then they are numerically solved using Runge-Kutta-Fehlberg-45 scheme. To gain a clear understanding of the current boundary layer flow problem, the graphical results of the velocity and thermal profiles, shear stresses at the disk, and Nusselt number are drawn. Results reveal that the increase in the value of the porosity parameter reduces the velocity of both particle and fluid phases.The increase in the value of the Biot number improves the temperature gradient of both particle and fluid phases. The rise in the value of the radiation parameter advances the heat transference of both phases. The rise in the value of the Biot number improves the rate of heat transfer. Finally, increasing the value of the radiation parameter improves the rate of heat transfer.
