Heat generation/absorption effects on radiative stagnation point flow of Maxwell nanofluid by a rotating disk influenced by activation energy

Abstract

This study reveals a Maxwell nanofluid flow with the effect of activation energy. The flow is generated by a stretching as well as swirling of the disk. For the formulation of heat transport mechanism, the Fourier's law of heat conduction is used with the addition of heat generation/absorption and thermal radiation. The von Karman's variables are employed to convert the partial differential equations (PDEs) into non-dimensional ordinary differential equations (ODEs). The numerical procedure is utilized in order to investigate the governing problem by a bvp midrich technique in Maple software. The involved different physical parameters are discussed through graphs and tables. Results reveal that the velocity enhances in the radial component and reduces in the azimuthal component. Further, the thermal profile enhances with the impact of thermal radiation and heat generation parameters, respectively.
