Course Length: 2 Hours

Purpose and Background

The goal of this webinar is to showcase the use of CFD as an alternative to traditional empirical models, to optimize the design or retrofitting of stormwater treatment units such as wet ponds, detention basins, storm filters, and hydrodynamic separators.

Primary Discussion Topics

• Stormwater treatment units
• Urban hydrology
• Particulate matter
• Water quality
• The use of CFD in water treatment

Learning Outcomes and Benefits

The audience will be introduced to multiple stormwater treatment technologies used in urban settings. Treatment units entitle both grey and green infrastructure units, each having varied levels of effectiveness. Compactional fluid dynamics is a technology that is gaining ever-growing acceptance among water practitioners as a valuable tool to help designing and/or retrofitting stormwater treatment units in a cost-effective manner. The performance of several stormwater treatment units will be simulated using CFD. A step-wise process comprising stormwater unit description and purpose, CFD model setup, simulation, and results post-processing will be showcased.

Upon completion of this course, you will be able to:

• Explain latest developments on CFD applications in the water industry.
• Explain about green infrastructure technologies in urban settings.
• Explain about the effectiveness of green infrastructure technologies improve water quality.
• Recognize CFD as a valuable tool to help optimize stormwater treatment design and reduce costly errors.
• Explore success stories where CFD has been applied resulting in project cost savings.
• Examine modeling techniques for stormwater treatment units.
• Explain the advantages and limitations of the use of CFD in the modeling of water treatment units.

Assessment of Learning Outcomes

Achievement of the learning outcomes by attendees will be assessed through a short post-assessment (true-false, multiple choice and fill in the blank questions) will also be administered.
