Chizhou Teachers college, Chizhou 247000, ChinaAbstract:The
CFD （Computational Fluid Dynamic） model for air blow tank
with machinery agitation is set up accurately by model tools,
the internal gas-liquid flows field is simulation using
two-phase Euler-Euler model. The analysis is focus on volume
fraction of air content and its velocity distributing according
to the simulation results, and compared the simulation results
with the data of sampling experimental datum. It has proven
that the CFD technology is valid for the simulation of air
blow tank with machinery agitation. So it should offer a
strong technological means for optimizing structure and
predicting the performance about this equipment.[著者文摘]
