Effects of cooling in transportation of viscous oil
• When heavy/viscous oil is cooled along the pipe, we expect density and viscosity to increase as temperature dropsdensity and viscosity to increase as temperature drops.
• 3D simulation is used to capture the cross-sectional effects.

The Importance of Using the Right Numerical Tools
• To be effective, simulations must be Fast enough to provide answers within the design timeframe– Fast enough to provide answers within the design timeframe
– Accurate enough to provide sufficiently insightful answers for better design decisions
• Choice and use of a judicious mix of tools for Multi-Fidelity Simulation to meet these effectiveness requirements, e.g.
1-D simulations (OLGA) for long pipeline systems– 1-D simulations (OLGA) for long pipeline systems– 3-D simulations (STAR) for equipment, transition regions– A user-friendly computing environment for activating the right mix
of tools for the situation being examined: co-simulation
