Marangoni convection in a C-shape enclosure with partially heated walls

A numerical study was carried out to investigate Marangoni convection of nanofluid in a C-shape cavity with partially heated walls at temperature Th. The opposite sides of the walls are cooled at constant temperature Tc while the rest of the partitions are kept adiabatic. The governing equations and boundary conditions are then introduced to describe the fluid flow and temperature distribution within the enclosure before the equations are non-dimensionalised and solved using the finite element method (FEM). The solutions, presented as streamlines, isotherms, local Nusselt and average Nusselt for varying Marangoni number, Ma, Rayleigh number, Ra and depth, d, are then discussed.
