MFIX Validation Studies, December 1994 to November 1995, CRADA No. PC94-026
Presented are validation results for MFIX, a finite difference, transient code that solves the equations of transport for interacting fluid and granular phases. The predictions of MFIX are compared to four different experimental studies involving the behavior of fluid beds. MFIX correctly predicts much of what is observed, for example, bubble formation, jet penetration lengths, solids circulation cells, mixing of gases and solids, transitions to different flow regimes, pressure and temperature fluctuations, and chemistry involving coal. Occasionally the details are imperfect; for example, the leading edges of bubbles often exhibit spikes, bubble frequency is higher than found experimentally, and flow regime transitions are displaced from the experimentally determined conditions.
