Multiphase Flow (Particle Tracking Analysis)

The flow of multiphase conditions including liquid-gas, liquid-liquid, granular, separated, and dispersed in complex geometries can be calculated by including additional multiphase models.

Even more complicated physics can be included, such as phase change, chemistry/reactions, dispersed phase breakup, and flow regime variation.

CFD Consulting Projects

Spray Quench Tower

Calculated the cooling, corrosion, and erosion effects of water spray using particle tracking and phase change models to capture the complex multiphase interactions on the internal surfaces of the quench tower.

Oil and Gas Pipeline (Flow Assurance)

Calculated the resulting turbulent fluid motion resulting from the mixing of black oil/natural gas and water in unusual operating conditions for undersea pipelines.

Flow Control Devices (FCD) and SAGD Liners

Predicted pressure drops and erosion in “Steam Assisted Gravity Drainage” bitumen recovery systems and production. This required modeling the multiphase bitumen-water emulsion flow through various flow control devices at downhole conditions, including the flashing effect for the SAGD extraction process.

Diesel Spray Injector

Modeled the spray injector to predict the cavitation location and rate. This was used to look at the implications on the resulting spray during the cyclic transient injection of a diesel injector.

Choke Valve

Calculates the multiphase flow rate across a choke valve at various pressures, corresponding gas oil ratios (GOR), and valve positions.
