Flow structures in bubbly flows with a tailored bubble size with and without liquid co-flow
, 2020 The aim of this thesis is to provide experimental data on bubbly flows for validation of Computational Fluid Dynamics simulations. Therefore, a new experimental facility was developed to study the interaction of two vertical, initially separated, parallel bubbly flows in a rectangular channel of 0.40×0.20×2.63 m (W×D×H).

Modeling of Bubbly Flow using a Combined Volume of Fluid and Discrete Bubble Model: Investigation on Interphase Forces [PDF]
Journal of Applied Fluid Mechanics, 2022 The gas-liquid two-phase flow with interfacial behaviors and bubble-liquid interactions is widely encountered in industrial processes such as that in gas-liquid reactors. The complicated phase structure makes it difficult to be modeled.

Nuclear Physics B, 2022 In this work we derive a class of geometric flow equations for metric-scalar systems. Thereafter, we construct them from some general string frame action by performing volume-preserving fields variations and writing down the associated gradient flow equations.

2D velocity vector profile measurement on bubbly flow using ultrasonic technique
Mechanical Engineering Journal, 2020 This paper describes a measurement technique for a two-dimensional (2D) velocity vector profile in the two-phase bubbly flow. The Ultrasonic Velocity Profiler (UVP) method, which is a nonintrusive technique applicable for real-time measurement, is ...

Interface Tracking Simulation for Subcooled Flow Boiling Using VOSET Method
Frontiers in Energy Research, 2021 This article presents a numerical simulation on subcooled flow boiling at a high-pressure condition. An interface tracking method, VOSET, was used to handle the moving interface, and conjugate heat transfer between the wall and the fluid was included in ...

Bubbles and Capital Flows [PDF]
SSRN Electronic Journal, 2002 This paper presents a stylized model of international trade and asset price bubbles. Its central insight is that bubbles tend to appear and expand in countries where productivity is low relative to the rest of the world. These bubbles absorb local savings, eliminating inefficient investments and liberating resources that are in part used to invest in ...

Bubble properties of heterogeneous bubbly flows in a square bubble column [PDF]
AIP Conference Proceedings, 2010 The present work focuses on the measurements of bubble properties in heterogeneous bubbly flows in a square bubble column. A four-point optical fibre probe was used for this purpose. The accuracy and intrusive effect of the optical probe was investigated first.
