Sub Cooled Boiling: Validation by Using Different CFD Models

In this work, simulation of a sub-cooled flow-boiling experiment[1] was undertaken using different boiling models implemented in the general purpose Computational Fluid Dynamics (CFD) code STAR-CCM+. Boiling can be modeled under the Eulerian-Eulerian framework using different models: Segregated Flow Multiphase model (EMP), Volume of Fluids (VOF) model, Transition boiling model, Mixture models (Drift Flux, Algebraic Slip models). We also investigated the effect of using different slip correlations available in literature within the mixture model on the predictions. It is seen that simulations predictions obtained using the different frameworks within the code are in fair agreement to experimental data.
