Journal ArticleDOI
Bubbly shock propagation as a mechanism for sheet-to-cloud transition of partial cavities
TL;DR: In this paper, the authors used high-speed visualization and X-ray densitometry measurements to examine the cavity dynamics, including the time-resolved void-fraction fields within the cavity.
Journal ArticleDOI
On the energy economics of air lubrication drag reduction
TL;DR: In this paper, the suitability of air lubrication for large ocean going and U.S. Great Lakes ships, by establishing the basic energy economic calculations and presenting results for a hypothetical air lubricated ship.
Journal ArticleDOI
On the scaling of air layer drag reduction
Brian R. Elbing,Simo A. Mäkiharju,Andrew Wiggins,Marc Perlin,David R. Dowling,Steven L. Ceccio +5 more
TL;DR: In this paper, the authors investigated air-induced drag reduction on a 12.9-m long flat plate test model at a free stream speed of. Measurements of local skin friction, phase velocity profiles (liquid and gas) and void fraction profiles were acquired at downstream distances to 11.5m, which yielded downstream-distance-based Reynolds numbers above 80 million.
Journal ArticleDOI
Time-resolved two-dimensional X-ray densitometry of a two-phase flow downstream of a ventilated cavity
Simo A. Mäkiharju,Céline Gabillet,Bu Geun Paik,Natasha A. Chang,Marc Perlin,Steven L. Ceccio +5 more
TL;DR: In this article, a two-dimensional X-ray densitometry system was developed to measure the void fraction distribution in gas-liquid flows, which is capable of acquiring a 2D projection with a 225 cm2 area of measurement through 21 cm of water.
Journal ArticleDOI
On the scaling of air entrainment from a ventilated partial cavity
Simo A. Mäkiharju,Brian R. Elbing,Andrew Wiggins,Sarah Schinasi,Jean-Marc Vanden-Broeck,Marc Perlin,David R. Dowling,Steven L. Ceccio +7 more
TL;DR: In this paper, the authors examined the behavior of a nominally two-dimensional ventilated partial cavity over a wide range of size scales and flow speeds to determine the influence of Froude, Reynolds, and Weber number on the cavity shape, dynamics, and gas entrainment rate.
