Abstract

The aim of the present work is to discuss the effects of magnetohydrodynamic (MHD) Marangoni convection flow of dusty TiO2 + H2O nanofluid past a flat surface. A two phase dusty nanofluid model is considered. The transformed dimensionless equations are solved numerically by 4thorder RK method together along with shooting technique. The outcomes of the current investigation are thatthe volume fraction, magnetic parameter and dust particle concentration parameter contribute decelerated motion. Dust particle concentration parameter plays a prime role in controlling the two-phase flow fields. Further, rise in magnetic parameter from 0.5 to 3 emaciates the heat transfer rate (HTR) by 18.45% while that of thermal dust parameter from 1.2 to 3.6 ameliorates HTR by 14 %.
