Gravity-driven surges of a viscoplastic fluid: An experimental study
Journal of Non-Newtonian Fluid Mechanics, 2009We present a new experimental setup dedicated to understanding the dynamics of gravity-driven freesurface surges made of viscoplastic fluids. It consists of a 3-m-long and 0.4-m-wide inclined channel whose bottom is constituted by an upward-moving conveyor belt with controlled velocity.

Theoretical and experimental studies of gravity wave interactions
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1967Abstract This paper is concerned with various aspects of the resonant interactions among waves. An experiment was suggested by Longuet-Higgins (1962) to detect this type of interaction among surface waves. This was subsequently performed by Longuet-Higgins & Smith (1966) and by McGoldrick, Phillips, Huang & Hodgson (1966). The

Experimental study on characteristics of gravity heat pipe with threaded evaporator
Thermal Science and Engineering Progress, 2021Abstract This work is for the first time an experimental study of thermal characteristics of an copper gravity heat pipe (thermosyrhon) with an outer diameter of 12 mm and a length of 230 mm with a threaded evaporator and freon R141b as working fluid under natural convection. The study demonstrates how a change in power input in the range from 5 W to

An Experimental Study of Boiling in Reduced and Zero Gravity Fields
Journal of Heat Transfer, 1961A pool boiling apparatus was mounted on a counterweighted platform which could be dropped a distance of nine feet. By varying the size of the counterweight, the effective gravity field on the equipment was adjusted between zero and unity. A study of boiling burnout in water indicated that a variation in the critical heat flux according to the one ...

Experimental study of Marangoni bubble migration in normal gravity
Experiments in Fluids, 2005Marangoni convection, whether thermal or solutal, is known to have a profound impact on many technological processes involving gas inclusions in a liquid phase. Evidently, similar phenomena may arise both in thermocapillary and solutocapillary situations, due to similarity of the motion driving mechanisms.

An experimental study of the dynamics of subaqueous sediment gravity flows
2005This paper examines the flow potential of subaqueous sediment gravity flows through a set of flume tests. The emphasis of the experiments was placed on clarifying the internal structure of fluidized sediment gravity flows in terms of a PIV technique.

Experimental study of gravity-driven dense suspension jets
Physics of Fluids, 2002This article presents experimental results from a study of a jet of dense suspension falling under gravity in a quiescent liquid bath of miscible liquid. The initial jet velocity v0 scales with the square of the initial jet diameter. Four different flow behaviors are observed. The jet remains cylindrical and stable when viscous forces are dominant.

The fall of charged particles under gravity: A study of experimental problems
Reviews of Modern Physics, 1992There are currently proposals to test the weak equivalence principle for antimatter by studying the motion of antiprotons, negative hydrogen ions, positrons, and electrons under gravity. The motions of such charged particles are affected by residual gas, radiation, and electric and magnetic fields, as well as gravity.

Experimental Study on Detached Solidification of Oil Under Gravity Condition
Journal of Superconductivity and Novel Magnetism, 2010In order to achieve detached solidification under gravity conditions, we conduct a series of experiments by using the water which is filled with CO2 gas and the oil whose solidification temperature is higher than water. When the tube (conical flask) is moved by the translation controller from hot region to cold region, the CO2 bubbles overflow from the
