Narrow Results

This paper discusses the impacts of velocity, temperature, and solutal slip on the mass and heat transfer characterization of MHD mixed convection Casson fluid flow along an exponential permeable stretching surface with chemical reaction, Dufour and Soret effects. The Casson fluid is supposed to flow across an exponentially stretched sheet, together with the exponential temperature and concentration fluctuations of the fluid. As governing equations, the momentum, energy and species concentration equations are constructed and represented as PDEs. Following that, these equations were converted via the similarity transformation into ODEs. Finally, the ODEs are numerically solved using the Keller-box method with MATLAB software’s algorithm. Expressions are produced for the fluid flow, temperature and concentration gradients. We also determined the physical variables from which the friction factor, rate of mass and heat transfer are attained for engineering purposes. Using graphs and tables, the impacts of altered physical characteristics on flow amounts are explored. The consistency and validity of our outcomes revealed a significant degree of agreement when comparing them to previously published studies. The findings reveal that raising the Soret and Dufour parameter enhances the velocity profile at the wall, but the converse is true for increasing the velocity slip factor.

The aim of this investigation is to arrange partial differential equations (PDEs) into simplified form for gradients (mass and thermal) in the inclined magneto hydrodynamic flow of hybrid (CuO–TiO₂/Water) nanoliquid in a permeable media. The modeled term is extremely nonlinear with the boundary conditions. So, this research focuses on numerical solution by using bvp4c solver in MATLAB software and by applying similarity transformation. Simulations have been done to discover the dynamics of stream and the transport of heat and mass under parametric deviation. To examine the impact of a temperature gradient on the transport of mass and the role of a concentration gradient on the transport of heat energy, outcomes have been documented in tabular form and shown through graphs. Remarkable changes in motion, temperature and concentration are noted when Dufour and Soret numbers vary.
