Nanoparticle Shapes (Sphere, Cylinder and Laminar) Impact with Dusty Carbon Nanotubes-Fluid in Magnetohydrodynamics Radiative Flow

Abstract

The idea of dust particles embedded on the MHD radiative flow of single walled carbon nanotubes-fluid (SWCNTs) and multi walled carbon nanotubes-fluid (MWCNTs) with different nanoparticle shapes along water, ethylene glycol and engine oil as based fluids has been investigated. Based on the typical shapes (sphere, cylinder and laminar), the rate of heat transfer is analysed in between fluid phase and dust phase for the velocity and temperature profiles for the first time. The partial differential equations (PDEs) are reformed into ordinary differential equations (ODEs) using similarity transformation and are solved numerically using Runge-Kutta Fehlberg method with shooting technique. With several parameters involved such as volume fraction of dust particle/nanoparticle, magnetic strength, thermal radiation and various nanoparticle shapes, it is found that the involvement of dust particle in carbon nanotubes-fluid (CNTs-fluid) has greater dynamic on heat transfer than a normal fluid. Moreover, the shape differences of nanoparticle resulting in different rate of the heat transfer. The impact of different shapes of nanoparticle are compared using fixed parameter values.
