Abstract
In the present study, flow of Diamond-Co3O4/ethylene glycol (EG) hybrid nanofluid towards a stretching sheet with stagnation point has been analysed under the influence of magnetic field and nonlinear thermal radiation. The catalytic property of homogeneous–heterogeneous reactions has also been included in the system. Additionally, the entropy generated in the system due to irreversible processes has been analysed here. The governing equations of the flow are obtained according to the given system and are converted to non-dimensional forms by using their appropriate similarity transformations. BVP4C tool of matlab has been utilised to solve these equations. Nature of various properties such as velocity, temperature and concentration of the flow with respect to different parameters has been represented graphically. Also a graphical comparison has been made between the nature of skin-friction and Nusselt number for hybrid-nanofluid and nanofluid respectively. The major outcome of the study is that the velocity profile of the fluid decreases for higher values of magnetic parameter. The temperature profile of the fluid enhances in the presence of nonlinear radiation. Also, the hybrid nanofluid was more efficient in transferring heat than the corresponding nanofluid. This work can be utilised by various large scale industries to increase their efficiency.
