Some Characteristics of a Propulsive Water Jet

Abstract

To obtain a high velocity, coherent, propulsive water jet, proper nozzle design is required. Existing high performance nozzles are considered, and a selected design is tested to provide optimization and performance data in the form of velocity and thrust loss with increasing jet standoff. An expression is developed to predict the velocity loss using an empirical friction factor value determined from the data.
