Numerical study of geyser events in rainstorm systems at different scales
Water Science and Engineering, 2023 Considering that we still do not fully understand the behavior of air pockets trapped in rainstorm systems and water flow changes inside pipes, the study of actual geysers presents many challenges.

Numerical modelling of air-water flows in sewer drops [PDF]
Water Science and Technology, 2017 The presence of dissolved oxygen (DO) in water flows is an important factor to ensure the aerobic conditions recognised as beneficial to preventing the occurrence of detrimental effects. The incorporation of DO in wastewater flowing in sewer systems is a process widely investigated in order to quantify the effect of continuous reaeration through the ...

A Stochastic Bubble Generator for Air-Water Flow Research [PDF]
38th IAHR World Congress - "Water: Connecting the World", 2019 Highly turbulent free-surface flows are often characterized by air entrainment, resulting in considerable flow bulking and a modulation of energy dissipation. An understanding of air-water flows remains constrained by instrumentation limitations, scale effects and few analytical developments. Whereas past attempts have addressed air-water flow research

The Experiment of Drying Process of the Fibrous Material [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2015 The article describes the experiment of water evaporation from fibrous material (cotton). The material is placed in the tube and hot air flows through (process of drying). Temperature of air is measured by thermocouple.

Experimental Stand for Very-Low-Velocity Gas Flow Generation
Sensors, 2023 This article presents an experimental stand for the generation of gas flows with very low velocities. The constant volume air flow was generated in the measurement area with the use of a Mariotte bottle and a water piston (water column in a tank).

Design and simulation of a new PCM heat exchanger for domestic hot water and air temperature control [PDF]
E3S Web of Conferences, 2020 Based on previous experiences which have proven the efficiency of PCM heat exchangers for air temperature control, we designed and simulated new PCM heat exchanger structures made of multiple PCM layers sandwiched between loading and discharge layers. By

Countercurrent air-water flow in two vertical channels. [PDF]
Journal of Nuclear Science and Technology, 1986 Experiments on countercurrent air-water flow were performed in two vertical channels with the same cross section as a BWR channel, but shorter channel length, which were interconnected with upper and lower plenums. Water and air were injected into the upper and lower plenums, respectively, and the air velocities in the two channels were measured.

Experimental setup to study two phase flows for environmental applications [PDF]
E3S Web of Conferences, 2019 The air water mix is a major concern for the environmental application. This paper proposes an experimental method to accede simultaneously at the water flow velocity field and at the void fraction. Instantaneous and mean fields, as well as the evolution

Air-water flows in partially-filled conduits [PDF]
Journal of Hydraulic Research, 1997 Supercritical open channel flows are characterised by a large amount of "white waters". Although free-surface aeration was investigated for steep chutes, flow aeration down partially-filled pipes received little attention. A re-analysis of partially-filled pipe data (VOLKART 1982, 1985) is presented.
