Abstract

The interfacial area transport equation for a subcooled boiling flow is developed with a mechanistic model for the wall boiling source term. It includes the bubble lift-off diameter model and the lift-off frequency reduction factor model. Those models take into account a bubble’s sliding on the heated wall after a departure from the nucleate site and the coalescences of sliding bubbles. To implement the model, the two-phase flow CFD code was developed, which is named as EAGLE (Elaborated Analysis of Gas-Liquid Evolution). The developed model and EAGLE code are validated by the experimental data of SUBO (Subcooled Boiling) facility. The computational analysis reveals that the interfacial area transport equation with the bubble lift-off diameter model agrees well with the experimental results. It presents that the source term for the wall nucleation enhanced the prediction capability for a multidimensional behavior of void fraction or interfacial area concentration. 1
