Casson nanoliquid flow with Cattaneo-Christov flux analysis over a curved stretching/shrinking channel

Abstract

In this study we investigated double diffusional Catteneo-Christov heat flux model to understand mass and heat transfer of liquid mix Casson nanofluid discharged over a curved shrinking/stretching channel. To govern such flow, a evenly charged force is applied in the vertical direction to the flow stream. Intensities of thermal and concentration fluxes are monitored by involving relaxations in Fourier's law. In the midst of mathematical modelling of our envisaged flow problem, we established a structure of complex partial differential equations embedded with sundry parameters. Using variable conversion procedure in vogue, these equations are transformed into simpler version of order differential equations. Numerical simulation is completed through MATLAB solver bvp4c by setting the default tolerance. The solver is applied recursively to achieve the desired accuracy in picking the best blend of the assorted parameters we entrenched in the system. We noticed thermal and concentration relaxations caused the temperature and concentration profiles to reduce, but thermophoresis enhances both fluxes. Casson and magnetic indicator parameters are responsible for slowing down the speed of the flow in case of stretching channels, moreover, adding amounts of these parameters produced less skin friction. Stretching/Shrinking and curvature of the bent channel played significant roles in behavioral modifications of various profiles and are therefore useful for future course of action.
