Product Development Example: Multiphase Flow Modeling

Many industrial processes involve the

simultaneous flow of multiple phases.

© 2011 ANSYS, Inc. September 8, 201119

Most of these processes are impossible to

observe directly. Therefore, engineers rely on

models and experiments to gain insight into

improving the efficiency, throughput, safety

and reliability of their processes.

Multiphase – Population Balance

DQMOM Population Balance captures the segregation of poly-dispersed phases due to differential coupling with the continuous phase (FL)
