Abstract
In this particular study, we have considered the flow of Casson fluid over inclined flat and cylindrical surfaces,
and have conducted a numerical analysis taking into account various physical factors such as mixed convection,
stagnation point flow, MHD, thermal radiation, viscous dissipation, heat generation, Joule heating effect, variable
thermal conductivity and chemical reaction. Flow over flat plate phenomena is observed aerospace industry, and
airflow over solar panels, etc. Cylindrical surfaces are commonly used in several applications interacting with fluids,
such as bridges, cables, and buildings, so the study of fluid flow over cylindrical surfaces is more important. Due
to the motivation of these applications, in this paper, a comparative study of fluid flow over these two surfaces
is considered. By applying appropriate similarity transformations, the governing PDEs of the problem have been
transformed into non-linear ODEs, which are solved by utilizing the Keller box technique. We have examined the
impact of distinct parameters by plotting velocity and thermal concentration graphs. All the profiles are plotted
in both cases of cylindrical and inclined flat surface. It has been observed that for higher Casson and Magnetic
parameter values, a decreasing velocity profile is noted for progressive values of the Eckert Number, thermal
conductivity parameter, Joule heating parameter, heat generation, and growth in temperature profiles are witnessed.
While the Prandtl number shows the opposite trend. Further, it has been observed that the concentration profile
declines for incremental observations of Schmidt number and chemical reaction parameters. Computed Local
parameters like the coefficient of skin friction for various values of Casson parameter and Curvature parameter,
Skin friction value increases for increasing observations of Curvature parameter the phenomena agree with
existing literature. Also, Nusselt number is calculated for various observations of curvature and variable thermal
conductivity parameters. Nusselt number decreases in magnitude with rising observations of varying thermal
conductivity argument at both flat and cylindrical surfaces. The values are matched with prevailing results and
noted a good agreement.
