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.

“…Analysis of second law of thermodynamics is a useful tool by which one can secure wastage of energy, predict the performance and fully utilize energy resources by minimizing the irreversibility, measured by entropy generation and get the optimal and improved efficiency of the thermal system. Many researchers employed the approach of minimizing entropy generation by taking diverse geometrical arrangements and many engineers have designed a thermal system to optimize, for instance, Butt et al (2012) showed that entropy generation rate can be abridged and precise as the slip which is present over a vertical plate. Guo et al The flow of non-Newtonian fluid over stretching and rotating surfaces has been focused by scientists and engineers as it has extensively important applications.…”

An investigation is performed for an alyzing the effect of entropy generation on the steady, laminar, axisymmetric flow of an incompressible Powell-Eyring fluid. The flow is considered in the presence of vertically applied magnetic field between radially stretching rotating disks. The Energy and concentration equation is taking into account to investigate the heat dissipation, Soret, Dufour and Joule heating effects. To describe the considered flow non-dimensionalized equations, an exact similarity function is used to reduce a set of the partial differential equation into a system of non-linear coupled ordinary differential equation with the associated boundary conditions. Using homotopy analysis method (HAM), an analytic solution for velocity, temperature and concentration profiles are obtained over the entire range of the imperative parameters. The velocity components, concentration and temperature field are used to determine the entropy generation. Plots illustrate important results on the effect of physical flow parameters. Results obtained by means of HAM are then compared with the results obtained by using optimized homotopy analysis method (OHAM). They are in very good agreement.

“…The entropy generation, ow, and thermal boundary layer over an isothermal stretching sheet are theoretically analyzed in the presence of the slip boundary condition and internal heat generation/absorption [31]. The e ect of hydrodynamic slip on entropy generation in a viscous ow over a vertical plate with convective boundary condition was observed by numerical technique, and shooting method [32].

Abstract. The application of second law of thermodynamics to an electrically conducting incompressible nano uid slip ow over a stretching sheet is investigated in the presence of thermal radiation and non-uniform heat source/sink, both analytically and numerically. The governing dimensionless equations for this investigation are solved analytically by hypergeometric function and numerically by using Runge-Kutta-Gill method with shooting technique. The e ects of magnetic parameter, nanosolid volume fraction parameter, slip parameter, and suction parameter on velocity pro le are discussed for Ag nanoparticles. Further, in addition to these parameters, the e ects of radiation parameter and non-uniform heat source/sink parameters on temperature pro le and entropy generation number are also discussed. Finally, the results of these pro les of Ag nanoparticles are compared with those of the Cu, Al2O3, and TiO2 nanoparticles. It is inferred that the e ect of slip and non-uniform heat source parameters decrease the entropy generation. The metallic nanoparticles create more entropy than the non-metallic nanoparticles.
