“…Further, Figure 2 is presented to validate the obtained results by comparing the numerical results of F η ( ξ , 0, 0) involving the effects of deceleration parameter ε = 0.000001 ε = 0.001 and ε = 0.1 with the previously established works by Chiam (1998) and Patil et al (2018b). It is found that the achieved results are in excellent agreement with these previous pioneering works.…”

“…Recently, Patil et al (2018a) have carried out a numerical study on steady triple diffusive mixed convection boundary layer flow past a moving vertical plate and have investigated the effects of Richardson number, ratio of buoyancy parameters and Schmidt numbers of both the solutal components on the fluid flow, thermal and species concentration fields. Also, Patil et al (2018b) have considered a numerical approach on steady triple diffusive mixed convection boundary layer flow along an exponentially decreasing external flow velocity in presence of suction/injection and their results indicate that the species concentration boundary layer thickness decreases with the increase of Schmidt numbers and that increases with the ratio of buoyancy parameters for both the species components. Further, Patil et al (2018c) have presented an analysis on unsteady triple diffusive mixed convection flow and who have explored the effects of time variable along a moving vertical plate.…”

Purpose The purpose of this study is to analyze the impacts of aqueous solutions such as NaCl-water and Sucrose-water on unsteady triple diffusive mixed convection flow along an exponentially decreasing external flow velocity in presence of suction/injection. Design/methodology/approach The proposed problem is modelled into dimensional partial differential equations which are nonlinear and coupled in nature. Non-similar transformations are used to transform these equations into non-dimensional form. To linearize the equations, quasilinearization technique has been used and then implicit finite difference scheme is used to discretise the linear partial differential equations. Findings The variations of various dimensionless parameters have been depicted on velocity, temperature and species concentration profiles for NaCl and Sucrose aqueous solutions through graphical representations. In addition, several results have been expressed through graphs pertaining to skin-friction coefficient, heat and mass transfer rates. The results indicate that the increase in Schmidt number raises the mass transfer rate for the case of NaCl-water and Sucrose-water solutions. Originality/value As per the authors’ best of knowledge, no investigations have been carried out in the literature on unsteady triple diffusive mixed convection flow along an exponentially decreasing mainstream velocity.

Purpose The purpose of this paper is to analyse the force convection laminar boundary layer flow on irregular boundary in diverging channel with the presence of magnetic field effects. Effects of various fluid parameters such as suction/injection, viscous dissipation, magnetic parameter and heat source/sink on velocity and temperature profiles are numerically analyzed. Moreover, numerically investigated on skin-friction and heat transfer coefficients when suction/injection occur. Design/methodology/approach The governing coupled partial differential equations are transformed to dimensionless form using non-similarity transformations. The non-dimensional partial differential equations are linearized by quasi-linearization technique and solved by varga's algorithm with numerical finite difference scheme on a non-uniform mesh. Findings The computation results are presented in terms of temperature, heat transfer and skin friction coefficients; these are useful for determining surface heat requirements. It was found that, in finite difference scheme for non-uniform mesh with quasi-linearization technique method gives smoothness of solution compared to finite difference scheme for uniform mesh, and this evidence is graphically represented in Figure 2. Originality/value The impacts of viscous dissipation (Ec) and magnetic parameter (Ha) on temperature profiles, skin friction and heat transfer are analyzed, which determine the heat generation/absorption to ensure the MHD flow of the laminar boundary layer on irregular boundary over a diverging channel.
