Numerical simulation of the flow of a chemical contaminant subjected to a jet impingement
Abstract
A numerical simulation and study are presented for characterization of the interaction flow of a water jet with a chemical contaminant droplet on a plane wall, which occurs in chemical decontamination processes. The model for this analysis is a twodimensional, twofluid flow governed by the NavierStokes equations. Emphases of the study are on the evolution of the contaminant droplet and the effects of variation of relevant flow parameters on the displacement of the contaminant. Computed results show that a jet impingement at an angle of incidence in the range of 45 deg  60 deg can achieve the highest cleaning speed of the contaminant. The results area can greatly improve the cleaning speed. However, for a given jet flow rate, it is more advantageous to increase the jet velocity rather than the crosssectional area in order to increase the efficiency of the use of jet fluid.
