Dynamics of Marangoni Convection in Hybrid Nanomaterials Flow With Dust Particles Random Motion

Abstract

Here we are working on the flow of dust particles in hybrid nanofluid. Marangoni convective flow of hybrid nanofluid is accounted by considering silver and copper as nanoparticles and water as base fluid. Dust particles and nanoparticles are used in this flow are spherical type. For thermal conductivity we have considered the Maxwell model. Porous medium is placed over a stretching sheet. Flow is generated via stretching sheet. MHD effects are also considered. Nonlinear equation of fluid phase and dust phase are converted in to ODE's by suitable transformations. These ordinary differential equations are solved numerically. Effect of involved dimensionless variables against velocity and temperature of hybrid nanofluid and dust phase, skin friction and Nusselt number of hybrid nanofluid is studied through graphs and tables. It is observed that temperature and velocity is more in case of hybrid nanofluid as compared to dust phase. Velocity of Ag-Cu water hybrid nanofluid enhances for greater mass concentration of dust particles. Velocity in both phase decay for higher porosity variable. Good match of results are seen by comparing current situation to earlier study in particular case.
