Abstract
This paper examined the three-dimensional steady thin film flow of tangent hyperbolic fluid with nonlinear mixed convection flow and entropy generation past a stretching surface under the influence of magnetic field. For the flow problem, the Cattaneo–Christov heat and mass diffusion model was employed to examine heat and mass transfer characteristics and impacts of the normally directed magnetic field. To transform nonlinear PDEs into ODEs, the variable transformation technique was used. The bvp4c algorithm was implemented to solve these ODEs. The behavior of every leading parameter on the velocities, temperature, concentration profile, entropy generation, and Bejan number was reported with tabular and figurative form. The results show that as the values of Br increase, the entropy generation enhances, but the Bejan number decreases. Moreover, as the values of B increase, the opposite characteristics are observed in entropy generation and Bejan number graphs. Furthermore, the skin friction coefficient number, local Nusselt number, and Sherwood number are graphically discussed for the active involved parameters. The best agreement is recorded when we compare this paper with the previous literature for various values of M .
Highlights
In physical sciences, one of the essential factors of flow of fluid which has very common applications is entropy generation
In case of thin film fluid flow, very little work is available in the literature. e entropy productions due to transmission of convective heating were reported by Bejan [1, 2] for the first time
Similar impacts have been presented by increasing both entropy generation number and Bejan number. at means, as we see from the figures, increasing the values of B resulted in enhancement of both entropy generation number and Bejan number of the problem under consideration

Is paper examined the three-dimensional steady thin film flow of tangent hyperbolic fluid with nonlinear mixed convection flow and entropy generation past a stretching surface under the influence of magnetic field. The Cattaneo– Christov heat and mass diffusion model was employed to examine heat and mass transfer characteristics and impacts of the normally directed magnetic field. E bvp4c algorithm was implemented to solve these ODEs. e behavior of every leading parameter on the velocities, temperature, concentration profile, entropy generation, and Bejan number was reported with tabular and figurative form. E results show that as the values of Br increase, the entropy generation enhances, but the Bejan number decreases. As the values of B increase, the opposite characteristics are observed in entropy generation and Bejan number graphs.
