Probabilistic Flow Regime Map Modeling of Two-Phase Flow [PDF]
, 2006 The purpose of this investigation is to develop models for two-phase heat transfer, void fraction, and pressure drop, three key design parameters, in single, smooth, horizontal tubes using a common probabilistic two-phase flow regime basis ...

Simultaneous capacitive probe and planar laser-induced fluorescence measurements in downwards gas-liquid annular flow [PDF]
, 2017 Various experimental techniques are available to analyse two-phase flows. The measurement concept and the applicability can however vary greatly. Prime examples from the opposite spectrum are planar laser-induced measurements (PLIF) versus capacitive ...

Similitude and scale effects of air entrainment in hydraulic jumps [PDF]
, 2008 A hydraulic jump is characterised by some strong turbulence and air entrainment in the roller. New measurements were performed in two channels in which similar experiments with identical inflow Froude numbers and relative channel widths were conducted ...

Air cavities at the inner cylinder of turbulent Taylor-Couette flow [PDF]
, 2018 Air cavities, i.e. air layers developed behind cavitators, are seen as a promising drag reducing method in the maritime industry. Here we utilize the Taylor-Couette (TC) geometry, i.e. the flow between two concentric, independently rotating cylinders, to

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]
, 2017 We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

Gaussian integral method for void fraction
ParticuologyA novel method, the Gaussian Integral Method (GIM), is presented for calculating void fractions in Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) simulations. GIM is versatile and applicable to various grid types, including structured and unstructured polyhedral meshes, without requiring special boundary treatments.
