The technology of leak protection and leak control while drilling through physical methods can be successfully applied based on studying the annulus' behaviour of the whole down hole flow field. In this paper, the model of sealing down hole while drilling through physical methods which will be used for CFD simulation is eatablished through reasonable simplification. Then running numerical simulation...
Based on computational fluid dynamic (CFD) method, flow field analysis and structural optimization of a three-phase hydrocyclone were carried out by using FLUENT soft pack. By numerical simulation analysis on de-gas and de-sand functions of the three-phase hydrocyclone, effect of different geometric parameters on de-gas and de-sand functions is studied. It is found that the change of overflow tube...
Based on the Navier-Stokes equations for viscous, incompressible fluid and VOF method, the numerical experiment platform of oil containment by rigid floating boom in wave is established, utilizing the commercial CFD software FLUENT, and the waves are generated by defining the velocity of water particle on the inlet boundary. The volume of fluid (VOF) model is used to distinguish the three immiscible...
The cavitating flow in nozzle holes is thought to be a very important factor to affect diesel fuel spray characteristics. In order to study the effect of cavitation on the internal flow of diesel nozzle, the 3d numerical simulation of cavitating flow developed fully in holes of a vertical four-hole VCO nozzle with mixture multi-phase cavitating flow model was carried out. The effects of injection...
A new kind of oil-mist collection is design to reduce the harm of oil-mist produced by cold-former to people and environment. This paper stimulates the flow field of air amplifier by using Fluent and obtains the speed vector by adopting the standard turbulence model and supplying air from different speed. It is validated that air amplifier is a perfect part of the oil-mist collection.
The flow field of hydrocyclone was simulated using commercial software FLUENT and Reynolds stress model in the paper. The results show that it correctly predicts the distribution rules of the velocity and the characteristics of Rankine-eddy. The simulation results are in good agreement with the experimental data published before, which proves the validity of mathematical model and computation method...
The aim of this paper is to present the multidisciplinary high resolution (grid size up to hundred meters) complex of numerical hydrodynamic-oil spill forward and backward models for the coastal zone simulation.
