Impact of non-linear heat source and magnetic field on the Carreau nanofluid Marangoni convective flow – a numerical investigation

Abstract

ABSTRACT A recent study examines the features of a dusty Carreau nanofluid over a flat surface with allowance for mixed convection that is not linear and heat radiation. It also examines how these factors affect fluid movement due to temperature differences (thermal Marangoni effect). The change in surface tension levels causes Marangoni convection, which finds applications in scientific areas like making crystals, keeping soap bubbles steady, drying thin wafers and dry silicon. Similarity transformations have been incorporated to create ODEs from PDEs. The complex non-dimensional differential equations are then solved using a numerical method called shooting method (with RKF-45 approach). For the momentum and heat distribution analysis, physical parameters are expressed in detail. The findings show that the Marangoni flow makes heat move quicker. In the same way, there is a decrease in the fluid’s velocity due to magnetic effects.
