Free surface aeration and development dependence in chute flows
Scientific Reports, 2022 The microscopic description of the mixture behaviour of air–water flow remains a challenge. It is not clear how to represent a complex two-phase interaction with the turbulent air–water structure development process. In this study, based on the air–water

Experimental Research on Aerated Supercavitation Suppression of Capillary Outlet Throttling Noise
Complexity, 2022 The aim of this work is the reduction of the throttling noise when the capillary is used as a throttling device. Based on the theory of bubble dynamics, two-phase flow, and aerated supercavitation, four different sizes of aerated devices used in ...

Supercritical flow at an abrupt drop: flow patterns and aeration [PDF]
Canadian Journal of Civil Engineering, 1998 Stepped waterways and cascades are common features of storm waterways, at dam outlets, and in water treatment plants. At an abrupt drop, open channel flows are characterized by the presence of shock waves and a substantial flow aeration. There is, however, little information on the basic flow characteristics.

Flow downstream of an aerator - aerator spacing [PDF]
Journal of Hydraulic Research, 1989 Cavitation erosion damage to spillway surfaces may be prevented with the use of aeration devices (aerators), introducing air in the layers close to the channel bottom. A study of the flow downstream of a spillway aerator was performed on the Clyde dam spillway model.

Water permeation simulation of autoclaved aerated concrete blocks using the Lattice Boltzmann method
Инженерно-строительный журнал, 2019 In this paper, the Lattice Boltzmann Method (LBM) is used to simulate the seepage field of autoclaved aerated concrete blocks. The macroscopic permeability coefficients of aerated blocks are obtained. The complex flow characteristics of the internal flow
