Modeling of Flow Interaction of a Liquid Jet with a Contaminant Droplet
Abstract
Two flow models have been developed for investigation of the flow interaction of a liquid jet with a chemical contaminant droplet on a plane wall. This interaction is considered as a two-dimensional viscous flow problem. Computer plots are presented for the flow pattern and the evolution of the droplet upon jet impingement. Displacements and mean velocity of the droplet upstream edge are provided as functions of jet velocity and fluid viscosity. These values may be used for evaluation of the efficiency of jet impingement for decontamination. Typical instantaneous pressure distribution of the impingement wall is also given. Studies in progress will establish correlations between flow parameters, such as the incidence angle and the diameter of the jet, and the performance of jet impingement. The present investigation involves utilization of jet impingement for chemical decontamination. The procedure is to use the great force produced by the impingement of jets to remove chemical contaminant droplets from surfaces of a vehicle or equipment.
