Introduction to air-water flows [PDF]
, 2018 For many hydraulic structures, safe operation can only be achieved if not only the characteristics of the water flow are considered, but due attention is also given to the simultaneous movement of air in the system. Although the difference in specific weight of air and water is so large that they are usually well separated by a sharp interface, a ...

Fluctuating Characteristics of Two-Phase Air-Water Slug Flow in Pressurized Pipelines [PDF]
آب و فاضلاب, 2009 Two-phase gas-liquid flows occur in a wide variety of situations, e.g., in chemical processing, power generation, water supply systems, and petroleum industry. The study of two-phase fluid flows is of great importance in hydraulic engineering.

Numerical Simulation of Poly-Dispersed Bubbly Flow Using a Multi-Fluid Model
Journal of Fluid Science and Technology, 2007 Numerical methods for predicting poly-dispersed bubbly flows in bubble columns are indispensable in the design of bubble column reactors. The objectives of the present study are (1) to experimentally investigate the effects of a bubble size distribution ...

Quantitative observation of co-current stratified two-phase flow in a horizontal rectangular channel
Nuclear Engineering and Technology, 2015 The main objective of this study is to investigate experimentally the two-phase flow characteristics in terms of the direct contact condensation of a steam–water stratified flow in a horizontal rectangular channel. Experiments were performed for both air–

Effects of Flow Regimes on Maximum Pressure in Offshore Pipelines [PDF]
مهندسی منابع آب, 2019 One of the most important factors in pipeline hydraulics and its protection against probable damages is keeping the pressure in a specific limit and also knowing how the pressure functions in the pipe through the pipeline route.

Re-Aeration on Stepped Spillways with Special Consideration of Entrained and Entrapped Air
Geosciences, 2018 As with most high-velocity free-surface flows, stepped spillway flows become self-aerated when the drop height exceeds a critical value. Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Fluids, 2021 The air–water interface in flowing systems remains a challenge to model, even in cases where the interface is essentially flat. This is because even though each side is governed by the Navier–Stokes equations, the stress balance which provides the ...

PROPAGATION OF DENSITY DISTURBANCES IN AN AIR-WATER FLOW [PDF]
Proceeding of International Heat Transfer Conference 3, 2019 Study investigated the behavior of density waves propagating vertically in an atmospheric pressure air-water system using a technique based on the correlation between density change and electric resistivity. This information is of interest to industries working with heat transfer systems and fluid power and control systems.
