Carbon Nanotubes (CNTs) Nanofluids Flow and Heat Transfer under MHD Effect over a Moving Surface

Abstract

The 2D steady flow of CNTs nanofluids and heat transfer over the moving plate through a uniform free stream under the effect of magnetohydrodynamics (MHD) is studied. The movement of plate is presumed in the opposite or same direction. A mathematical modelling that is governed by a system of partial differential equations (PDEs) subjected to boundary conditions is transformed into a system of nonlinear ordinary equations (ODEs). An attempt at finding the expected outcomes is successfully executed by solving ODEs system using MATLAB bvp4c solver. The effect of various parameters such as magnetic field, CNTs volume friction and moving parameter on velocity and temperature profile, skin friction, Nusselt number and heat transfer rate are investigated numerically. The results are presented using tabular and graphical illustration. From the results, the increment of magnetic field into the flow will increase in both the skin friction and the heat transfer coefficient. Besides that, non-unique solutions are obtained when the plate moves in the range of and . For comparing the performance of base fluid, kerosene works better than water as a base liquid. We are also showing that SWCNTs is more effective both in the skin friction and the heat transfer coefficient compare to MWCNTs.

Time-Depending Flow of Ternary Hybrid Nanofluid Past a Stretching Sheet with Suction and Magnetohydrodynamic (MHD) Effects

“…Consequently, MHD fluid, with its capacity to regulate cooling rates, can serve as the quiescent fluid [17]. Samat et al, [18] conducted a numerical study on the MHD effect within carbon nanotubes nanofluid over a moving surface. Their findings revealed a direct correlation between the magnetic field intensity and the heat transfer rate, as well as skin friction.…”

Magneto-hydrodynamic boundary layer flow and heat transfer of hybrid carbon nanotube over a moving surface

“…In recent years, numerous researchers have studied the boundary layer flows caused by moving surfaces on different fluids such as nanofluids [11][12][13][14], carbon nanotubes [15][16][17], hybrid nanofluids [18][19][20] and hybrid carbon nanotubes [9]. Sakiadis [21] has studied the classical problem of the boundary layer flow resulting from a continuously solid moving surface moving at a constant velocity.…”
