“…This force is parallel to the plate's surface and declines exponentially in the horizontal way to the surface, after exercising via the Boussinesq approximation, along with a boundary layer approximation. The condition in the model was used to create the following leading system of equations (Equations (1) to (4)) [42,43].…”

Entropy generation and dual solutions are rarely studied in the literature. An analysis is attempted here. More exactly, the present paper looks at the impact of radiation of a micropolar fluid on mixed convective flow containing the titanium alloy Ti 6 Al 4 V nanoparticle along with a Riga plate. The study of dual-nature solution for the entropy generation along a Riga surface was not being explored in the literature; therefore, the current model focuses on the dual solutions of this complex nature model. Riga surface is identified as an actuator of electromagnetic in which electrodes are accumulated alternatively. This array produces the behavior of electromagnetic hydrodynamic in the flow field. The transmuted leading equations were worked out through the formula of 3-stage Lobatto IIIA. Influences of exercising enormous parameters on temperature distribution, velocity, and micro rotation fields are portrayed and argued. More than one solution is achieved in opposing flow, while in the phenomenon of assisting flow result is unique. Moreover, due to the micropolar parameter, the separation of the boundary layer is decelerating. It is determined that the entire structure produces the dual-nature solution of the phenomenon of stagnation point flow, and the temperature profile behavior shows the significant enhancement in the thermal conductivity due to the addition of the nanoparticle. The results exposed that liquid velocity is enhanced, and micro rotation is decelerated, by improving the values of Hartmann numbers in both solutions, whereas the temperature field is decelerated in the first solution and accelerated in the second solution.

The numerical study of EMHD laminar flow of Bingham fluid flowing among two Riga plates with thermal radiation has been established. Both the Riga plates, upper and lower, are taken as stationary. Constant heat transfer is considered for both Riga plates. The governing equations for the problem have been transformed into dimensionless non-linear PDEs by using usual transformations. The obtained non-dimensional PDEs have been solved numerically by applying the explicit FDM. MATLAB has been conducted for the numerical simulation. The stability analysis stated that the governing equations will be converged for 0.09, r P  1.00 , 40, 40 mn = and  = 4.00 respectively.Finally, a comparison with several published results has been discussed.

“…They analyzed the impact of different thermophysical variables on the momentum, thermal, and concentration distributions. Hayat et al studied rotational flow of nanofluid in terms of heat transfer, viscous dissipation and heat generation. Khan et al presented the numerical study on Entropy Generation through thermodynamics second law and found that Entropy number increases with Weissenberg number, Hartmann number and chemical reaction variable while decreasing trend is observed for Bejan number.…”

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.
