Flow Regime Visualization and Identification of Air-Water Two-Phase Flow in a Horizontal Helically Coiled Rectangular Channel [PDF]
, 2021 Experiments of flow regime visualization and identification of air–water two-phase flow were conducted in a horizontal helically coiled rectangular channel. The test superficial liquid and gas velocities are 0.09–2 m/s and 0.18–16 m/s, respectively. Flow

Science and Technology of Nuclear Installations, 2015 In earlier study we have demonstrated that RELAP5 can predict flow instability parameters (flow rate, oscillation period, temperature, and pressure) in single channel tests in CIRCUS-IV facility. The main goals of this work are to (i) validate RELAP5 and

TWO-PHASE FLOW REGIME IDENTIFICATION THROUGH LOCAL TEMPERATURE MAPPING [PDF]
Proceeding of Second Thermal and Fluids Engineering Conference, 2017 Two-phase flows underpin some of our most ubiquitous technologies, ranging from micro-scale liquid-liquid cooling of electronics to macro-scale liquid-vapour boiling and condensation in thermal power plants. Establishing the morphology of a two-phase flow, under a prescribed set of conditions, is considered particularly important in the design stage ...

Flow Regime Identification of Gas-liquid Two-phase Flow Based on HHT [PDF]
Chinese Journal of Chemical Engineering, 2006 Abstract A new method to identify flow regime in two-phase flow was presented, based on signal processing of differential pressure using Hilbert Huang transform (HHT). Signals obtained from a Venturi meter were decomposed into different intrinsic mode functions (IMFs) with HHT, then the energy fraction of each intrinsic mode and the mean value of ...
