Characterization of Flow Interaction of a Water Jet with a Chemical Contaminant Droplet

Abstract

Two flow models are developed for the study of the interaction of a water jet with a chemical contaminant droplet on a flat surface which occurs in chemical decontamination processes. The interaction flow is considered as a two- dimensional viscous flow. Computer-generated plots are presented to show the flow pattern and the evolution of the contaminant droplet with various viscosities. The effects of the jet incidence angle and the jet velocity on the movement of the droplet are described. The computed result shows that the instantaneous impact pressure peak on the contaminated surface can rise much higher than the corresponding steady-state dynamic pressure of the jet.
