“…The addition of MHD flow studied by Vinodkumar Reddy et al, 28,29 Vinodkumar Reddy and Lakshminarayana, 30 and Reddy and Lakshminarayana [31][32][33] gives thermal management a dynamic component that allows for precise fluid flow control in metallurgical processes. Slip factor and activation energy have an impact on the Sherwood number and velocity profiles, as observed by Naz et al, 34 Bodduna et al, 35 and Ali et al 36 The complex interactions between these variables and how they affect the generation of entropy are of utmost importance. Sharma et al [37][38][39] and Rao et al 40 studied hybrid nanofluid flow with the Soret and Dufour effect, squeezing motion analysis and diffusion thermo effect and investigated that elevated radiative heat and the presence of a heat source contributes to the elevation of nanofluid temperature, while an increase in the thermal radiation parameter corresponds to an augmentation in the Nusselt number.…”

The multieffect bioconvective heat transfer in porous media is essential for many technological applications. However, the literature governing practical applications is very scarce. The bioconvective transport of magnetohydrodynamic cross nanofluid carrying oxytactic microorganisms across a flexible cylinder with velocity slip, viscous dissipation, thermal radiation, and chemical reaction with a heat source in Darcy–Forchheimer porous medium is predicted in this piece of work. The random movement and thermophoresis processes are revealed by the Buongiorno model. Using a suitable similarity transformation and boundary layer approximation, the simplified model equations are converted into coupled highly nonlinear ordinary differential equations (ODEs). The resulting ODEs are dealt with numerically utilizing the BVP4C and the shooting method with predetermined thermal radiation, heat source, chemical reaction, and so forth parameters. The velocity field is inversely influenced by the Forchheimer number and porosity parameter. The Sherwood number is significantly influenced by chemical reactions. For heat source parameter (S) and increasing radiation parameter (Rd), the Nusselt number increases and convection is shown for the value of Rd near about 3. Overall, this study will help researchers in science and engineering to understand the intricate and multieffective dynamic system and industrial applications like microbiology, and biodynamical systems, biological tissues, biofilms, soil, or filter media.

In the current numerical simulation, the thermal transfer of viscous incompressible time dependent MHD free convective flow of hybrid nanofluid (Cu-TiO2-H2O) over a vertical porous plate with viscous dissipation and thermal radiation is examined. The system of partial differential equations which controls the fluid flow are transmuted into dimensionless equations and are solved using numerical simulation namely Galerkin Finite Element Method. The momentum and thermal consequences, coefficient of heat transfer and skin friction with Gr, M, Ec, N, t, ωt, δ2, λ – parameters for both nanofluid (Cu-H2O) and hybrid nanofluid (Cu-TiO2-H2O) flows are exposed through graphs and tables. It is revealed that heat transfer coefficient of Cu-TiO2-H2O is more effective when compared with Cu-H2O flows varying with aforementioned parameters. The current numerical computation is in good agreement with the analytical solution of the problem. This study is used in several engineering fields such as electronic cooling, heat exchangers, nanomaterial processing, environmental engineering, chemical industry.

In the current study, cross-temperature and concentration gradients are used to model the in a binary fluid contained in an angled square cavity. Using a method, the , , and conservation equations were numerically solved. The inclined cavity under equal solutal buoyancy and thermal forces was the subject of the study . Since the horizontal components of the thermal and singular volume forces were equal but opposed to one another, an equilibrium solution for this situation that corresponds to the rest state of the immobile fluid is feasible. However, this equilibrium solution becomes unstable above a specific critical value of the , leading to vertical density stratification inside the enclosure. The results are shown using the and as well as the and for the flow intensity. The existence of the commencement of convection is demonstrated in this work, and both natural and anti-natural flow solutions are obtained. Subcritical convection has also been seen for the natural solution when the is more or less than unity. For the start of supercritical and subcritical convection, the number's critical values are identified. As the climbed, so did the flow's intensity and the rates at which heat and mass were transferred. Reducing flow intensity and accelerating mass transfer are the results of raising the . Different flow patterns are shown for an aspect ratio of 4, and the existence interval of the oscillatory solutions is calculated.
