Natural nonlinear convection of dusty fluid in a suspension of multi-wall carbon nanotubes nanoparticles with different temperature of water and suction

Abstract

This study addresses the nonlinear free convective flow of a conducting dusty nanofluid (multi wall carbon nanotubes + water + micrometer sized dust particles) over a stretched cylinder at different temperatures (10 °C and 50 °C) in the presence of Cattaneo-Christov heat flux, heat source. The mainly arising equations of motion such as continuity, momentum and energy are simplified with the suitable dimensionless variables and solved numerically using the Runge-Kutta method. A numerical simulation is executed with inclusion of multi-wall carbon nanoparticles and dust particles into different temperatures (10 °C and 50 °C) of base fluid water. Calculations for the wall friction coefficient and Nusselt number are carried out and demonstrated in tables. To authenticate the attained results we have offered the comparison with the already published results. A few graphical pictures are plotted to scrutinize the physical insight of the numerically modeled problem for the several flow parameters and found that the multi-walled carbon nanotubes + water at 10 °C dusty nanofluid shows better heat and mass transfer rate compared to temperature at 50 °C. Due to nonlinear convection the friction factor is reduced in the presence of the magnetic field. The Biot number encourages the wall friction, heat and mass transfer rates of both cases.

The impact of thermal stratification and heat generation/absorption on MHD carreau nano fluid flow over a permeable cylinder

“…Non-Newtonian power-law fluids flowing over a wedge with heat source/ sink in presence of viscous dissipation deliberated by Kishan et al [24], Here, the uniqueness of current effort is to study the velocity, temperature nanofluid stratification enforced in the fluid flow system of magneto hydrodynamic (MHD) Carreau fluid flow models. Recently, the various investigators [25][26][27][28][29][30][31][32][33][34][35][36] are considered magneto hydrodynamic with the various flow configurations (disk, stretched surface, cylinder, symmetric and asymmetric flow) and various physical parameters (suction, Multiwall carbon nanotubes, nanoparticles, non-Fourier heat flux). With their studies highlighted that the non-Newtonian fluid has tendency to control the flow performance.…”

Dusty Nanofluid Past a Centrifugally Stretching Surface

“…e flow of dusty fluid due to linearly stretching cylinder has been deliberated by Konch and Hazarika [13], and MHD oscillatory flow of dusty fluid in a rotating porous upright canal was studied by Chand et al [14]. Very recently, Balasubramanian et al [15] discussed natural nonlinear convection flow of dusty fluid over a stretched cylinder at dissimilar temperatures. Furthermore, Abbas et al [16] inspected the influences of slip on the flow of a dusty fluid over a porous expanding surface.…”
