Numerical Simulation of the Gas-Liquid Flow in a Square Crosssectioned Bubble Column
- CHISA 14th International Congress of Chemical and Process Engineering
, 2000
"... ntrary to the other case only little temporal behaviour was found. This disagrees with the strongly time dependent flow, which was observed experimentally. In the simulation the bubble plume moves into one corner and stays there for the rest of the simulation time. This resulted in asymmetric veloci ..."

Hotspots and mantle plumes: some phenomenology
- J. Geophys. Res
, 1990
"... The available data, mainly topography, geoid, and heat flow, describing hotspots worldwide are examined to constrain the mechanisms for swell uplift and to obtain fluxes and excess temperatures of mantle plumes. Swell uplift is caused mainly by excess temperatures that move with the lithosphere plat ..."

Housing supply and housing bubbles
- Journal of Urban Economics
, 2008
"... Like many other assets, housing prices are quite volatile relative to observable changes in fundamentals. If we are going to understand boom-bust housing cycles, we must incorporate housing supply. In this paper, we present a simple model of housing bubbles which predicts that places with more elast ..."

Elastic bands: Connecting path planning and control
- In: Proceedings of the International conference on robotics and automation (ICRA
, 1993
"... Elastic bands are proposed as the basis for a new framework to close the gap between global path planning and real-time sensor-based robot control. An elastic band is a deformable collision-free path. The initial shape of the elastic is the free path generated by a planner. Subjected to artificial f ..."

forces, the elastic band deforms in real time to a short and smooth path that maintains clearance from the obstacles. The elastic continues to deform as changes in the environment are detected by sensors, enabling the robot to accommodate uncertainties and react to unexpected and moving obstacles. While

CHAPTER 128 ANALYSIS OF AIR-BUBBLE PLUMES
"... Models are developed to describe the gross behavior of air-bubble plumes generated by point and line sources of air-bubbles released in stagnant water bodies of uniform density. The models predict plume width, velocities, and induced flow rates as a function of elevation above the source. The analys ..."

Bubble Plumes, Bubbles, and Wave Characteristics from Wind- Steepened, Breaking Waves
"... Breaking wave-generated bubbles are important to many geophysical processes of direct impact on climate, in particular air-sea gas exchange. It is well established that the air-sea exchange rates of most greenhouse gases significantly increases at high wind speeds, when breaking waves and bubble plu ..."

plumes disrupt the sea surface. This increase is closely related to the bubble distribution [Schudlich and Emerson, 1996]. However, few studies have related the formation bubble distribution and bubble-plume characteristics with wave evolution and development. To fill this gap, as part of the LUMINY
Ensemble correlation PIV applied to bubble plumes rising in a bubble column
, 1999
"... This paper discusses an ensemble correlation, double-exposure single-frame, particle image velocimetry (PIV) technique that can be applied to study dispersed gas-liquid two-phase flows. The essentials of this technique will be reviewed and several important issues concerning the implementation of th ..."
