Description
Summary:Jet mixing is one of the simplest methods to achieve mixing. There have been a number of experimental studies concerned with jet mixing. Most of these studies end up in empirical correlations. In the past, there have been only a few attempts towards computational fluid dynamics (CFD) modeling of jet mixed tanks. Further, these CFD models have not been validated by detailed comparison with experimental measurements. In view of this, the present work deals with development of a CFD model and a detailed comparison with experimental measurements. From the results, it is clear that the CFD model predicts overall mixing time fairly well. However, the concentration profiles as a function of time at various locations in the vessel are not predicted well. The reasons for this are explored and attempts have been made to improve the predictions of concentration profiles.
