| Application: CFD Helps Develop Faster Oil Containment Boom |

Researchers have used CFD to improve the speed at which an
oil containment boom may be towed. Boom velocity is the determining factor in oil spill cleanup time because the boom can fail under hydrodynamic load.
Using software from Fluent Inc., the CFD analysis focused on effects such as relative oil-water velocity, physical properties of oil and water, water depth, and boom draft.
Using software to simulate the interaction between oil, water, and boom offers a less expensive alternative to channel testing, thereby reducing the cost of designing improved oil booms. Once they have a validated CFD model, researchers can quickly change the boom geometry and evaluate design alternatives. Using CFD, researchers have now identified a type of boom that has the potential to increase critical velocity by more than a factor of four. When implemented, the new net-boom structure will decrease the time needed for oil spill cleanup, protecting the environment from the effects of the oil.

AEA Technology has boosted the performance of their
CFX-4 breed of solver. Long known for its strengths in the chemical process and multiphase arena, CFX-4.4 has been updated with multiple frame of reference capability as well as improved parallel performance.
Other valuable enhancements include a new free-surface modelling tool that tracks accurately the gas/liquid interface through grid movement. For combustion applications, a multi-grey gas capability has been included, allowing more accurate calculation of radiative heat transfer in furnaces.

Researchers at the University of Hannover are using STAR-CD to predict sub-surface currents, wakes, and propeller jet impingement on waterway banks and beds.
Damage to waterways from ship activity requires expensive repair work to correct.
“The results are very promising and we feel that the knowledge gap in this area is closing so
that engineers will be able to better protect our waterways in the near future”
