Chemical response in Oldroyd-B liquid through rotational disk with temperature and space-related heat rise

This paper considered the magnetized flow of an Oldroyd-B fluid over a rotational disk. In this investigation, the altered Fourier’s law rather than the classic Fourier’s law of consideration was used by the fluid thermal features. Its effect on homogeneous–heterogeneous reactions about mass transport was studied. Additionally, interesting characteristics of thermal radiation with temperature and space-related heat sources or sinks were examined. The von Karman variables were utilized to discipline the PDEs toward non-dimensional ODEs. An efficient finite element method was utilized in acquiring the numerical results. The correlation table was invented in an indentured case to save the efficacy of their numerical outcomes in the previous results. It was noticed that the fluid velocity decreases to make an effect on the relaxation time parameter. The thermal distribution on Oldroyd-B fluid displays the diminishing trend on acceleration on the range of thermal relaxation heat flux parameter. Further, higher values of heat generation parameter decline the rate of heat transfer. Furthermore, the absorption rate of the fluid deteriorates a greater strength of the homogeneous reaction.
