Abstract

A numerical study has been performed to determine evaporation rate from the surface of a binary mixture of ethanol and iso-octane (i.e. E0, E10, E20, E85) owing in 2D rectangular ow domain having dimensions (400x533)Fim2. The liquid and gas phases are owing in counter-current direction. VOF multiphase model was used to model stratified two-phase ow. The vapour/liquid equilibrium pressure was calculated using SIMPLEC model. A parametric study with dfferent inlet and exit conditions was performed. Two dimensional ow domain subjected to boundary condition as velocity inlet and pressure outlet is modeled using ICEM CFD. This model is imported into commercial CFD solver ANSYS FLUENT 12.0.1, undergoing multiphase ow preceding with Vof model implemented upon a single Droplet and then on Multi-Droplet ow domain, keeping in mind that the droplet near to the inlet, evaporates earlier as compared to the droplet away from the inlet boundary.
