Description: Tatweer Petroleum intends to purchase the electrically driven, oil-flooded screw compression packaged units to compress Casing Vapour/Gas Recovery (CVR) from a low pressure field
gathering system that collects well head casing gas from several hundred wells and compress the gas into a higher gas pressure transport network.
oil and gas corporation to qualify its Fluoroloy[R] sealing solutions and polymer materials to enhance oil recovery for an ultra-high pressure field
in the Gulf of Mexico, contributing chemical compatibility tests with requirements for 20,000 psi pressure (20K) valve qualification.
So the simulation results such as the pressure field
, velocity field near the bend while the projectile passing through the bend are examined to analyze the influence of the deflection angle on the projectile penetration.
Both capture the recirculation of the airflow and the low-pressure region at the center of the plenum while only very small differences can be observed in the pressure field
. Considering these results together with the tile-airflow predictions, we conclude that the time-splitting method in our FFD implementation delivers essentially the same accuracy as the SIMPLE scheme in traditional CFD, at least, in this application.
Here, [rho] is the density of fluid, U is the velocity vector of the fluid, subscript m is the gas-phase and the liquid-phase mixture extent, and p is the pressure field
. Assume that both phases share the same pressure field
The discretized momentum equation was solved to compute the intermediate velocity field and the pressure field
computed by the pressure correction equation that exploits the discrete momentum equation to replace the velocity field in the continuity equation with a pressure term.
The aim of the present work is to find numerical values of a pressure field
in the gap between the piston and the cylindrical bore.
(1) Studies on Driver's Vision Pressure Field
. As a part of "Human-Vehicle-Road" circle, road infrastructures will influence the whole driving environment.
Initial conditions, mimicking the present-day distribution of both temperature and pressure field
, were imported from the calculated best-fitting time step (i.e., 125,000 years of simulation time) of the previously performed natural state simulation.
One most important source of unsteadiness is the potential effect in which the pressure field
associated with the leading edge of a blade sweeps past the trailing edge of a vane .
As the pressure gradient increased, the pressure field
showed more significant variations.
