Effects of Polydispersity in Bubbly Flows [PDF]
, 2010 This thesis concerns the dynamics of bubbly flows with a distribution of equilibrium bubble sizes. The main goal is to formulate the physical and numerical models of continuum bubbly flows that enable us to efficiently compute the average mixture ...

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 ...

Turbulent bubbly flow in pipe under gravity and microgravity conditions [PDF]
, 2012 Experiments on vertical turbulent flow with millimetric bubbles, under three gravity conditions, upward, downward and microgravity flows (1g, -1g and 0g), have been performed to understand the influence of gravity upon the flow structure and the phase ...

Experimental Study of Bubbly-Slug Flow Transition Criteria in an Vertical Circular Tube by Using WMS
Frontiers in Energy Research, 2020 Two-phase flow is an important and common phenomenon in reactor systems, and there are significant differences in the heat and mass transfer characteristics of two-phase flow under different flow patterns.

The Fluidization Backwash Method of Filter Beds by Air-water Bubbly Flow
Journal of Water and Environment Technology, 2020 A novel fluidization backwash method by the air-water bubbly flow with air bubbles of various sizes has been proposed for rapid filters. The backwash efficiency is closely related to the bubble wake motion.
