- Abstract
The current study explores the magnetized flow of an Oldroyd-B fluid by a rotating disk. In this analysis, we use the modified Fourier's law instead of classical Fourier's law to study the fluid thermal features. The impact of homogeneous–heterogeneous reactions for mass transport is also considered. The von Karman variables are used to convert the partial differential equations into non-dimensional ordinary differential equations. The BVP Midrich scheme is utilized to acquire the numerical solution. Diverse effects of various involved parameters on the velocities, temperature and concentration of the liquid are analyzed. Additionally, the comparison table is made for limiting case to see the validity of our numerical results with the past outcomes. It is observed that the fluid velocity reduces with the impact of relaxation time parameter. Further, higher values of thermal relaxation time decline the fluid temperature. Moreover, with an increase in homogenous reaction, the concentration boundary layer thickness becomes thinner. The reduction in wall concentration gradient is noticed against homogeneous reaction rate.
