摘要: Foam lift is one of the most cost effective methodologies for unloading gas wells. The surfactants are either injected intermittently or continuously to lift the liquid to the surf... 查看全部>>关键词: Critical velocity under foam flow Pressure gradient Foam unloading potential Liquid holdup...
Measurements of rising velocity of a small bubble in a stagnant fluid in one- and two-component systems Despite its apparent simplicity, the problem of accurate determination of the shape and velocity of a bubble in a still fluid is far from being solved. Mos... GP Celata,F D’Annibale,...

However, open ponds present liquid heights between 15 and 30 cm, thus requiring a high ground surface area in order to process high volume loads. As such, their implementation is suited for the outskirts of small towns or nearby waste producing industrial areas. This last case would be ideal...
It is based on removing desired soluble constituents from a solid or semisolid matrix using a suitable liquid phase [11]. The process consists of the mixture of the solvent with the natural material for a specific period, sufficient to ensure the migration of the solute from the solid matrix...
At the former, which is labelled by “Gate to the die cavity” in Figure 1, we set zero normal gradient conditions for the velocity, the temperature and the liquid fraction; thus, respectively, (𝐧𝑂·∇)𝐔=0,nO·∇U=0, (9) 𝐧𝑂·∇𝑇=0,nO·∇T=0, (10) ...
In this relation, w ¼ vs À vn is the difference between the velocity of the superfluid and normal components, which can be generated by slowly rotating the atomic cloud so that the critical velocity of the superfluid is not reached anywhere in the trap. Equation (1) has been used to...
aThe use of surfactants or foam for de-watering liquid loaded gas wells is by changing the liquid into a bubble film the surface area exposure is increased, the density is decreased, the surface tension is decreased and the net impact on the critical velocity calculations is usually a ...
