Summary: This paper discusses a mathematical model for the two-dimensional flow of tangent hyperbolic nanofluid over a Riga plate in the presence of gyrotactic microorganisms. The governing non-linear partial differential equations are transformed into a system of non-linear ordinary differential equations using a set of pertinent transformations. The numerical solutions of the dimensionless equations are obtained using the bvp4c technique, and the numerical results are presented using the bvp4c tool in MATLAB. The graphical representations show the effects of various parameters on concentration, velocity, temperature, and motile microorganism profiles. The study concludes that increasing the variations of mixed convection parameters enhances the velocity of the tangent hyperbolic fluid, a larger Prandtl number reduces the temperature of the nanofluid, the concentration of nano particles is enhanced by growing activation energy parameters, and the microorganisms profile is improved with the first-order velocity slip parameter while decaying for bio-convection Lewis number.

Summary: This investigation focuses on the mathematical modeling and interpretation of a non-Newtonian tangent-hyperbolic rheological model that captures multiple physical effects. The study analyzes the flow under nonlinear buoyancy forces and magnetohydrodynamics with convective heating. Various factors such as thermal radiation, Ohmic dissipation, heat generation, convective conditions, Soret-Dufour aspect, and double stratification are considered in the energy and concentration expressions. The results show the opposite impacts of the Dufour number on temperature and heat transportation rate, and the increase in Soret number leads to higher solutal field and lower mass transportation rate.

Summary: This study investigates magnetohydrodynamic (MHD) bioconvection Walter-B nanofluid flow due to a stretched sheet, considering the significance of motile gyrotactic microorganisms and melting phenomena. By using the homotopy analysis method to handle nonlinear ODEs, convergent series solutions are obtained. The results show that velocity intensifies with an increase in melting and viscoelastic parameters, while it decays against the magnetic parameter; temperature decreases against the melting and radiation parameters, but increases for higher Brownian motion parameter and Prandtl number; concentration increases with the Brownian motion parameter, but decreases against a higher melting parameter.

Summary: The ISPH method is used to analyze the effects of a magnetic field on thermosolutal convection of solid particles spreading within a finned cavity. The simulations show that solid particles tend to move towards the upper part of the cavity and the fins on the upper wall play a role in adjusting the spread of the particles. The blending between solid and fluid particles is influenced by an increase in the Hartman parameter, while the Soret and Dufour numbers reduce the blending of solid particles within a nanofluid flow.

Summary: The study investigates the impact of double diffusion, activation energy, Brownian motion, thermal radiation, thermophoresis, viscous dissipation, magnetic field, and Joule heating on bioconvection of a tangent hyperbolic nanofluid flow over a vertical stretching porous surface containing microbe. The fluid transport equations are solved using the finite difference method and the effects of key parameters on the fluid's transport properties are depicted in graphs and tables. It is observed that higher dimensionless activation energy leads to a decrease in mass transfer rate at the stretched nanomaterial sheet, and the concentration of the nanofluid near the sheet decreases with an increase in the porosity parameter value, but the opposite behavior is observed far from the sheet.

Summary: This study aims to analyze the heat transfer behavior of the MHD micropolar dusty hybrid nanofluid in the presence of a heat source/sink and linear thermal radiation over a three-dimensional surface. A novel implementation of an intelligent numerical computing solver based on MLP feed-forward backpropagation ANN with the Levenberg-Marquardt algorithm is provided in the current study. Dusty hybrid nanofluid has a greater influence than dusty fluid, and improving the values of the vortex viscosity and fluid-particle interaction parameters increases the rate of heat transfer. The temperature profile of dusty and dusty hybrid nanofluid rises for higher values of the thermal radiation parameter.
