This manuscript investigates the effects of viscous dissipation, Ohmic heating, nonlinear thermal radiation, chemical reactions, Hall current, and ion slip on mixed convection flow magnetohydrodynamic (MHD) Casson nanofluid over a vertically stretching sheet in spongy medium. The strongly ordinary differential equations (ODEs) derived from governing are solved using sixth-order, seven-stage Runge–Kutta (RK6) method conjunction with shooting technique. Numerical simulations conducted an open-source Python programming language. study evaluates temperature, velocity, nanoparticle concentration, skin friction coefficients, Nusselt number (rate heat transfer), Sherwood mass transfer) based dimensionless parameters. Key findings reveal that increasing currents enhance velocity profile x-direction, while parameter exerts diminishing effect. fluid temperature decreases higher parameter, values but increases due to ratio Eckert number. Furthermore, reaction Schmidt reduce concentration within boundary layer, amplifying this also examines rates mass, heat, momentum transfer near surface under varying influences, presenting results through comprehensive graphs tables. To validate numerical method, comparative analysis is against previous studies, demonstrating excellent agreement thus confirming reliability accuracy computational approach.

This study investigates the complex interplay between radiation and magneto-flow on a porous, perpendicular plate immersed in viscoelastic Maxwell fluid. The significance lies understanding how Lorentz force shapes dynamics energy transfer such systems, which is crucial for various industrial applications. Utilizing comprehensive model that accounts heat generation absorption, we transform partial differential equations into ordinary ones through flow similarity analysis, providing valuable insights system's behavior. Employing bvp4c solver MATLAB, evaluate velocity profiles fluid flow. Graphical representations allow thorough examination of influence thermophysical parameters. Our findings reveal an intensified profile attributed to prolonged material relaxation times. Furthermore, temperature progressively increase with higher porous These results hold significant implications applications, particularly fluids' transport studies. Insights from this research can inform design optimization systems as ovens, boilers, cross-flow exchangers, solar panels, enhancing efficiency performance. Overall, contributes novel advance beyond previous efforts literature, paving way further exploration field. primary finding indicates Rayleigh number increases, experiences increase, whereas shows decrease.

This study focuses on understanding the bioconvection in Jeffery–Hamel (JH) flow, which has valuable applications areas like converging dies, hydrology, and automotive industry, make it a topic of practical importance. research aims to explore Homogeneous–Heterogeneous (HH) chemical reactions magnetic Darcy–Forchheimer model with convergent/divergent channels. To analyze role porosity, law is applied. The main system equations simplified through similarity transformation into ordinary differential solved numerically help NDSolve technique. results, compared previous studies for validation, are presented graphs tables. reveals that divergent channels, velocity decreases higher solid volume fractions, while convergent increases. Furthermore, various physical parameters, such as Eckert number porosity parameter, increase skin friction channels but decrease These findings suggest parameters investigated this can effectively enhance homogeneous reactions, providing insights applications.
