Aliran Lapisan Sempadan Magnetohidrodinamik dalam Karbon Nanotiub merentasi Plat Bergerak dengan Kesan Gelinciran dan Radiasi Terma

Abstract

Momentum and thermal boundary layers stimulated by magnetohydrodynamic flow (MHD) on moving plate surface in single and multiwall carbon nanotubes (SWCNT and MWCNT) with slip and thermal radiation effects were studied. The mathematical modelling is developed to derive the governing partial differential equations. These models were transformed into a system of nonlinear ordinary differential equations via similarity transformation, which are then solved numerically using the boundary value problem with fourth-order accuracy (bvp4c) solver in MATLAB software. The effects of relevant parameters such as nanoparticle volume fraction, magnetic field, slip and thermal radiation on heat transfer are analyzed and discussed. It is found that dual solutions exist in opposing flows. The study also found that the heat flux on the moving plate increased with the increasing in slip effect. Also, the heat transfer rate in SWCNT-water is higher than that of MWCNT-water.
