Aspects of Uniform Horizontal Magnetic Field and Nanoparticle Aggregation in the Flow of Nanofluid with Melting Heat Transfer

Abstract

The current exploration focuses on the impact of homogeneous and heterogeneous chemical reactions on titanium dioxide-ethylene glycol (EG)-based nanoliquid flow over a rotating disk with thermal radiation. In this paper, a horizontal uniform magnetic field is used to regularise the flow field produced by a rotating disk. Further, we conduct a comparative study on fluid flow with and without aggregation. Suitable transformations are used to convert the governing partial differential equations (PDEs) into ordinary differential equations (ODEs). Later, the attained system is solved numerically by means of the shooting method in conjunction with the Runge–Kutta–Fehlberg fourth-fifth-order method (RKF-45). The outcome reveals that the fluid flow without nanoparticle aggregation shows enhanced heat transport than for augmented values of melting parameter. Furthermore, for augmented values of strength of homogeneous and heterogeneous reaction parameters, the mass transfer is greater in fluid flow with aggregation conditions.

“…Anantha Kumar et al 34 studied the MHD Cattaneo-Christov flow with variable heat source/sink over a cone and wedge. The study of non-Newtonian MHD fluid flow with heat absorption/consumption along different geometries was analyzed by [35][36][37][41][42][43][44][45][46] . Anantha Kumar et al 38 studied the MHD fluid Williamson with variable heat source/sink and chemical reaction on a curved/apartment surface.…”

Three-Dimensional Swirling Flow of Nanofluid with Nanoparticle Aggregation Kinematics Using Modified Krieger–Dougherty and Maxwell–Bruggeman Models: A Finite Element Solution

“…The investigation's findings indicated that the case of liquid flow with NP aggregation demonstrated increased heat transfer in comparison to improved heat source/sink parameter values. The influence of NP aggregation and other influencing factors on the NF stream on different surfaces was investigated by Wang et al [17,18]. The findings indicated that the heat transfer efficiency in the case of flow dynamics with NP aggregation was enhanced for higher values of the radiation parameter.…”
