Casson Nanofluid Flow with Cattaneo-Christov Heat Flux and Chemical Reaction Past a Stretching Sheet in the Presence of Porous Medium

In the current work, inclined magnetic field, thermal radiation, and the Cattaneo-Christov heat flux are taken into account as we analyze the impact of chemical reaction on magneto-hydrodynamic Casson nanofluid flow on a stretching sheet. Modified Buongiorno’s nanofluid model has been used to model the flow governing equations. The stretching surface is embedded in a porous medium. By using similarity transformations, the nonlinear partial differential equations are transformed into a set of dimensionless ordinary differential equations. The numerical solution of transformed dimensionless equations is achieved by applying the shooting procedure together with Rung-Kutta 4th-order method employing MATLAB. The impact of significant parameters on the velocity profile $f(\zeta )$, temperature distribution $\theta (\zeta )$, concentration profile $\phi (\zeta )$, skin friction coefficient $(C_f)$, Nusselt number $(N{u}_x)$ and Sherwood number $(S{h}_x)$ are analyzed and displayed in graphical and tabular formats. With an increase in Casson fluid $0.5<\beta <2$, the motion of the Casson fluid decelerates whereas the temperature profile increases. As the thermal relation factor expands $0.1<{\gamma }_1<0.4$, the temperature reduces, and consequently thermal boundary layer shrinks. Additionally, by raising the level of thermal radiation $1<Rd<7,$ the temperature profile significantly improves, and an abrupt expansion has also been observed in the associated thermal boundary with raise thermal radiation strength. It was observed that higher permeability $0<K<4$ hinders the acceleration of Casson fluid. Higher Brownian motion levels $0.2<Nb<0.6$ correspond to lower levels of the Casson fluid concentration profile. Moreover, it is observed that chemical reaction $0.2<{\gamma }_2<0.5$ has an inverse relation with the concentration level of Casson fluid. The current model’s significant uses include heat energy enhancement, petroleum recovery, energy devices, food manufacturing processes, and cooling device adjustment, among others. Furthermore, present outcomes have been found in great agreement with already published work.
