Free surface bubbly flow in an open capillary channel [PDF]
npj MicrogravityThis study investigates bubbly flow in a rectangular open channel under microgravity. A homogeneous flow model is used to compute frictional pressure loss and then establish a correlation between the drag coefficient and mass quality, leading to a one ...

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 ...

Bubble, bubble, flow and Hubble: large scale galaxy flow from cosmological bubble collisions [PDF]
Journal of Cosmology and Astroparticle Physics, 2010 We study large scale structure in the cosmology of Coleman-de Luccia bubble collisions. Within a set of controlled approximations we calculate the effects on galaxy motion seen from inside a bubble which has undergone such a collision. We find that generically bubble collisions lead to a coherent bulk flow of galaxies on some part of our sky, the ...
