Abstract
The generalised multifluid modelling approach (GEMMA) was developed and implemented in OpenFOAM at the University of Leeds to deal with different interfacial scales in multiphase flows. The interface between two phases is tracked by adding an interface-resolving capability in the cells occupied by large interfaces, whilst the model reverts to a standard multifluid formulation in the regions of small/dispersed interfaces. In this work, the GEMMA model is further developed to predict the condensation process of a steam bubble in subcooled liquid flows and heat transfer from steam to a liquid through the interface in a turbulent stratified flow. Comparison of the simulation results with experimental data demonstrates that the model predicts well the behaviour of a condensing bubble, as well as heat transfer in the turbulent stratified flow. Overall, the results indicate that the extended GEMMA model provides an accurate predictive tool for heat transfer in multiphase flows.
