Monodisperse bubbly flows with ANSYS CFX and OpenFOAM: A comparison


Monodisperse bubbly flows with ANSYS CFX and OpenFOAM: A comparison

Kriebitzsch, S.; Rzehak, R.; Lucas, D.

Within the framework of two-fluid modelling, the interfacial transfer processes needs to be modelled by suitable closure relations. Based on previous experience with ANSYS CFX (e.g Rzehak and Krepper, 2013) a set of closure relations applicable for adiabatic bubbly flow has been implemented in OpenFOAM. Great effort has been made to match all details of the models so that the same results may be expected and residual differences should be only due to different numerical procedures.
In this work we compare simulation results for dispersed gas-liquid pipe flow with experimental data given by Liu (1998) as well as in-house data obtained with the MTLoop facility described in Lucas et al. (2005). Overall, the experimental data are reasonably well predicted and the predictions are competitive with the results computed with ANSYS CFX. However some differences can be observed, especially in the turbulent quantities in the near wall region
