Bubble and Foam Module

Theory

Bubble entrainment, foam transfer rate and burst rate are formulated based on empirical formulas developed in a previous study. Details will be documented in Malej et al. 2023 (in preparation).

Model configuration and input

  1. Modify Makefile with -DFOAM

  2. Specify parameters related to bubble and foam entrainments, etc.

PLOT_INTV_FOAM = <float number> (default: same as PLOT_INTV)
BurstRate = <float number> (default: 0.01)
MinThick = <float number> (default: 0.01)
TransferRate = <float number> (default: 0.1)
CdFoam = <float number> (default: 0.5)

  1. An example is provided in /rip_2D_foam/. The figure below shows the model result from default parameters.
