Abstract
This paper presents the study of heat and mass transfer in two-dimensional magnetohydrodynamic nanofluid flow over a cone/plate. By linearization and finite difference discretization, we numerically solved ordinary differential equations obtained from the partial differential equations (PDEs) by using similarity transformation. The impact of non-dimensional parameters, such as Prandtl number, Dufour number, Schmidt number, and Soret number, on velocity, temperature, and concentration has been examined from the graphs and tables. It has been noted that, compared to the rotating plate, heat and mass transfer properties of the flow over the rotating cone are more promising.
Highlights
The study of nanofluids has great application in the fields of medicine, electronics, and heat transfer devices
Nadeem and Saleem10 investigated the analytical solution of unsteady, Newtonian, and convective flow over a rotating cone estimated in the presence of a magnetic field
Xuan16 mentioned that because of Brownian motion, relative motion of a nanofluid and base fluid has ultimate effects of thermal conductivity, which is the reason for the immense importance of convective transport of nanofluid flow
Summary
The study of nanofluids has great application in the fields of medicine, electronics, and heat transfer devices. Fluids with particle sizes of 1 nm–100 nm are known as nanofluids and belong to a latest class of fluids These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. It was mentioned that the thermal conductivity of the fluid enhanced twice by adding a small quantity of nanoparticles into conventional heat transfer liquids. Hering and Grosh and Himasekhar and Sarma investigated heat transfer from a rotating vertical cone embedded in a porous medium by free and forced convection. Raju and Sandeep discussed mass and heat transfer of bio-convection flow over a rotating plate/cone. Xuan mentioned that because of Brownian motion, relative motion of a nanofluid and base fluid has ultimate effects of thermal conductivity, which is the reason for the immense importance of convective transport of nanofluid flow
