An impact of CNTs on an MHD Casson Marangoni boundary layer flow over a porous medium with suction/injection and thermal radiation

The current work employs the single wall and multiwall carbon nanotube models to investigate the effect of suction and injection over a Marangoni boundary layer flow on magnetohydrodynamics (MHD) Casson fluid and thermal radiation on a permeable surface. The nonlinear partial differential equations (PDEs) produced by the governing equations for the prescribed flow are translated using the proper similarity transformations into a system of nonlinear ordinary differential equations (ODEs). The consequential nonlinear equation is solved analytically by using incomplete Gamma function. The effects of suction and injection over velocity profile and temperature distribution are presented graphically. It was found that the heat transfer rate increased due to increases in the volume fraction. In addition, the applied magnetics energy, on the other hand, causes it to decrease. Further, single wall carbon nanoliquid has a higher temperature than multiwall nanoliquid. The problem under consideration has a wide range of commercial and scientific applications in various industries like aviation and medicine field. The impacts of MHD and suction/injection on the flow and heat transfer properties of the fluid are examined under the influence of radiation, and the solution of each profile is shown in the form of figures along with the outcomes of the interface velocity and heat transfer rate at the surface.
