A nonbarotropic continuum bubbly mixture model is used to study the one-dimensional cavitatingjow through a converging-diverging nozzle. The nonlinear dynamics of the cavitation bubbles are modeled by the Rayleigh-Plesset equation. Analytical results show that the bubble/bubble interaction through the hydrodynamics of the surrounding liquid has important effects on this conjined JEow jield. One...

In this paper numerical analysis of the condensing steam flow in a converging-diverging nozzle is investigated. The ANSYS Fluent results are compared with in-house academic Computational fluid dynamics code respect to capacity for thermodynamic assessment. “local” real gas equation state used as mathematical complement governing equations code. code, functions well and water physical properties...

In this study the wetting behavior of converging-diverging and diverging-converging capillaries is investigated numerically using an in-house written, finite-element code. An interface tracking procedure based on the predicted change in the total liquid volume, to update the interface location, and Cox's formulation, to determine the dynamic contact angle and the interface shape, is proposed an...

Supersonic gas jets produced by converging–diverging nozzles are commonly used as targets for laser–plasma acceleration (LPA) experiments. A major point of interest these is the density at region interaction where laser ionizes plume to create a plasma, providing structure. Tuning profiles this crucial LPA optimization. “flat-top” profile desired line control propagation and high-energy electro...

This paper presents the experimental results the choked flow characteristics of a subcritical refrigerant through a converging-diverging nozzle. A test nozzle with a throat diameter of 2 mm was designed and developed. The influence of operating conditions on the choked flow characteristics, i.e., the pressure profile and mass flow rate under choked flow conditions are investigated. The results ...
