Eulerian modelling of turbulent bubbly flow based on a baseline closure concept


Eulerian modelling of turbulent bubbly flow based on a baseline closure concept

Liao, Y.; Ma, T.; Liu, L.; Ziegenhein, T.; Krepper, E.; Lucas, D.

A unified set of closures have been applied to simulating different configurations and fluids, i.e. pipe flow and bubble column, air/water and air/metal liquid. The simulated velocity, void fraction and turbulence profiles were compared with the measured ones. Starting from the baseline model for poly-disperse flows the present work is intended to prove the performance of a recently published model for bubble induced turbulence. New knowledge assisting in model assessment and development has been achieved on the basis of experimental and direct numerical simulation investigations. A brief discussion on the further development and future work regarding Eulerian closure models was given.
