“…From Figures 2 and 3, it is noticed that the present results are correlated with the existing results and then we concluded that the implemented numerical technique is accurate and valid for further calculations. From Table 2 it can be concluded that the present results are exactly matched with Ramprasad et al 44 in the absence of energy equation, thermal buoyancy, and heat source.…”

The flow through asymmetric nonuniform (convergent) channels with the effect of the magnetic field have a pronounced impact in engineering and biological fields such as chemical and food industries, blood flow through capillaries, and arteries, and so forth. With this motivation, the present study focuses on convective hydromagnetic particulate suspension flow in an asymmetric convergent channel under the heat generation effect. The numerical method is applied to solve the nondimensionalized equations governing the transport process of fluid and particle flow and its heat. To check the convergence of the computational results, a grid independence test has been performed. A comparison test has been made to validate the results and an admirable agreement is noticed with published results. Computation results are reported for the influence of emerging parameters on the fluid as well as particle velocity and temperature profiles through graphs and tables. A method of slope linear regression through data points is presented to study the impact of various parameters on skin friction and Nusselt number.

“…When Re=0.9, the particle velocity increases. This behavior is seen in Ramprasad et al [17].From fig 9 it can be noted that the particle velocity decreases for R=0.5,2.5,3.5. Further when R=5.0 the particle velocity shoots up.…”

To validate the method, present results are compared with Ramprasad et al [17] as shown in Table-1 It is interesting to note that the buoyancy effect is more near left wall compared with that of the right wall.In order to illustrate the influence of slip parameter s1 on the fluid velocity fig 6 is plotted. An increment in s1, enhances the fluid velocity in entire channel.…”

In this article an attempt has been made to dscuss the velocity and temperature slip effects on MHD convective two phase particulate suspension flow in a convergent channel with viscous dissipation .The non dimensionalised governing equations are solved using Runge-Kutta shooting method.The results obtained are represented graphically for various emerging parameters.The skin friction coefficient and Nusselt number are obtained and validated with existing results.It is found that with an increase in velocity slip parameter the velocity of the fluid increases.The fluid phase temperature decreases with an increase in temperature slip parameter.

The flow field in a convergent-divergent engulfment along with the installation of infinite cylinders as an obstacle results in non-linear partial differential equations and the scientific computation in this regard remains a challenging task. The present attempt is the numerical motivation in this direction to evaluate the flowing liquid stream in the convergent-divergent channel at a low Reynolds number. From the left wall, the liquid stream move with the parabolic profile and have interaction with the case-wise installation of infinite cylinders in the left vicinity of the convergent-divergent throat. The differential system is constructed for the flow field in the channel and hybrid meshed finite element method is utilized to report the numerical solution. A comparative study is enclosed for the hydrodynamic forces faced by obstructions in the left region of the convergent-divergent throat. The drag coefficient for a triangular cylinder acting as an obstruction is higher than that of a circular hitch. In comparison to both triangular and circular hitches, the square-shaped obstacle suffered the most drag force. Considering drag coefficient one can extend this work to obtain information for the real behavior of the vehicle toward air flow and may conclude findings toward reduction of fuel consumption.
