Impinging Performance of High-Pressure Water Jets Emitting from Different Nozzle Orifice Shapes
Geofluids, 2020 The impinging pressure of a water jet is a key factor in engineering applications, and the jet shape has a great influence on this pressure. In this paper, five different nozzle shapes were designed, and impacting tests were conducted based on a self ...

A Physical Interpretation of Stagnation Pressure and Enthalpy Changes in Unsteady Flow [PDF]
Volume 7: Turbomachinery, Parts A and B, 2009 This paper provides a physical interpretation of the mechanism of stagnation enthalpy and stagnation pressure changes in turbomachines due to unsteady flow, the agency for all work transfer between a turbomachine and an inviscid fluid. Examples are first given to illustrate the direct link between the time variation of static pressure seen by a given ...

Definition of vortex boundary using stagnation pressure
Physical Review FluidsA novel method is proposed to identify vortex boundary and center of rotation based on tubular surfaces of constant stagnation pressure and minimum of the stagnation pressure gradient. The method is derived from Crocco's theorem, which ensures that the gradient of stagnation pressure is orthogonal to both the velocity and vorticity vectors.
