A CCD camera technique was developed to measure instantaneous particle velocities in a thin bubbling bed for fluidization of 530 μm glass beads. The hydrodynamic were computed by averaging the over velocity space using concepts kinetic theory. Laminar-type stresses and granular temperatures from measurement velocities. Bubblelike measured Reynolds normal per unit bulk density vertical direction 8 times larger than lateral because higher fluctuations particles bubble-flow region. sum shear...
Methane hydrate, a potential future energy resource, is known to occur naturally in vast quantities beneath the ocean floor and permafrost regions. It important evaluate how much methane recoverable from these hydrate reserves. This article introduces theoretical background of HydrateResSim, National Energy Technology Laboratory (NETL) production simulator for hydrate-containing reservoirs, originally developed NETL by Lawrence Berkeley (LBNL). describes mathematical model that governs...
Cubic Equations of State (EoSs) typically provide unreliable predictions for phase density and derivative properties at the high-temperature, high-pressure (HTHP) conditions associated with ultradeep petroleum reservoirs (that is, temperatures to 533 K pressures 241 MPa). The perturbed-chain statistical associating fluid theory (PC-SAFT) EoS returns improved but still can overpredict experimental value by up 5% HTHP conditions. Not surprisingly, when a modified set pure-component PC-SAFT...
Abstract Bubbles were simulated in a two-dimensional fluidized bed with constant inlet velocity using two computer codes, the IIT code and MFIX code. The computational results compared to Jung et al. (Citation2005) experiments thin bubbling of 530 μm glass beads. use higher order numerics produces better bubble resolution due smaller numerical diffusion. computed sizes their distributions agreed experiments. simulations show that there is no formation for sufficiently elastic particles. CFD...
This study presents methods for accurate viscosity modeling using the frictional theory (f-theory) and free volume (FV theory) of at temperatures to 533 K pressures 276 MPa, which are high-temperature, high-pressure (HTHP) conditions associated with ultradeep porous sandstone or carbonate layers that retain crude oil natural gas. The perturbed-chain statistical associating fluid (PC-SAFT) equation state (EoS), HTHP-volume-translated (VT) Peng–Robinson EoS,...
Oil and gas wells are generally drilled with the intention of forming a filter cake on wellbore walls to primarily reduce large losses drilling fluid into surrounding formation. Unfortunately, formation conditions frequently encountered that may result in unacceptable despite type employed created. It is extremely important optimize thickness as very thick can cause stuck pipe and other problems. The focus this research use computational dynamics (CFD) technique numerically simulate vertical...
This study reports the high-temperature, high-pressure density data for propane, squalane, and their binary mixtures five compositions at temperatures to 520 K pressures 260 MPa. The measurements are obtained with a floating-piston, variable-volume, view cell. From data, isothermal isobaric excess molar volumes upon mixing computed. For mixture studied here, volume is mostly negative, showing minimum 0.6550 mole fraction of propane becomes less negative as concentration increases....
