The two-phase flow in a short horizontal channel of a rectangular cross-section with the height of 100–500m and width of 9–40mm was studied experimentally. The use of the Schliren and fluorescent methods made it possible to reveal the flow of liquid in the channel and to determine its ...
Two-phase flow in pipes develops various flow regimes for either horizontal or vertical pipes depending on the relative mass flow rates of vapor and liquid. Provided here is a brief introduction to the subject. Flow regimes are defined descriptively such as: • Bubbly = bubbles distributed relat...

Two-phase flow patterns in spirally fluted tubes were investigated through visual observation. Both straight (horizontal) and coiled fluted tubes were studied using adiabatic flow of air and water in transparent castings. The same types of patterns which occur in smooth tubes (i.e. annular, strat...
The aim of the present work is to visualize flow regimes in air–water two-phase flows and propose a flow regime map for such flows in vertical mini pipes. The neural network technique is implemented to recognize and predict a gas–liquid, two-phase flow pattern in mini tubes, having ...
Therefore, this paper proposes a gas-solid two-phase flow regimes identification method based on electrostatic sensors and the CB-ResNext network. Firstly, composite electrostatic sensors are employed to collect electrostatic signals. Then, leveraging the characteristics of the MTF (Markov Transition ...
In this work, a new flow regime transition model is proposed for two-phase flows in a vertical annulus. Following previous works, the flow regimes considered are bubbly (B), slug (S) or cap-slug (CS), churn (C) and annular (A). The B to CS transition is modeled using the maximum...
In this work, a high speed ultrasonic multitransducer pulse-echo system using a four transducer method was used for the dynamic characterization of gas-liquid two-phase separated flow regimes. The ultrasonic system consists of an ultrasonic pulse signal generator, multiplexer, 10 MHz (0.64 cm) ult...
