Turbulence Modeling for Modern Industrial CFD

8-9 July 2017 0800-1700 hrs



This course covers the fundamentals of turbulence modeling, beginning with the various equation systems and modeling strategies. Theoretical backgrounds are presented for second-moment closure and practical models are presented and demonstrated. Simplifications and alternative eddy-viscosity modeling strategies are considered that are practical for every-day engineering calculations in an industrial environment. Suitable transient approaches are also considered, including several of the most popular hybrid RANS/LES approaches, as well as recent advances in areas such as synthetic turbulence. The agenda will cover a wide variety of turbulence modeling techniques with practical examples of each. Students will have the opportunity to participate in running several example cases using easy-to-use demonstration software on the machines provided.

Key Topics

  • Understanding of the fundamental second-moment equations
  • Basic modeling strategies for unknown higher-order terms
  • Simplified closures via eddy viscosity concepts
  • Advanced non-linear eddy-viscosity models
  • Advanced Hybrid RANS/LES models, including synthetic turbulence

Who Should Attend

This course is aimed at beginner or intermediate engineers using industrial CFD codes. Traditional and currently popular classes of turbulence model are explained from the fundamentals with no prior knowledge of modeling required. Hands-on training allows participants to test out various models and modeling options to gain experience that can be used in their own fields of work or research.

Paul Batten
Dr. Paul Batten has many years’ experience in the numerical and physical modeling of fluid dynamics and turbulence. He received his Ph.D. from Southampton University, England, before taking up a position at the Manchester Metropolitan University, where, as a Senior Research Scientist, he worked on the modeling of flow-induced resonance inside cavities and weapons bays. In 1995, Dr. Batten joined UMIST's department of Mechanical Engineering as an Honorary Lecturer working on a British Aerospace funded project to develop anisotropic turbulence closures for high-speed jet and afterbody flows. In 1999, Dr. Batten joined Metacomp Technologies, Inc. As a Principal Scientist at Metacomp, he has been developing modeling practices for unsteady flows and acoustics and is leading the development of the acoustics software suite, CAA++, along with major contributions to the development of CFD++, including Riemann solvers, turbulence modeling and hybrid RANS/LES. Dr. Batten acts as reviewer for a number of international scientific journals and has more than 60 refereed publications in the form of journal and conference proceedings.

Dr. Uriel C. Goldberg
Dr. Goldberg is a Principal Scientist at Metacomp Technologies. Before joining Metacomp in 1996 he served as a Research Associate at UMIST, Manchester, England. His previous experience includes 13 years of research and development positions at Rockwell Science Center, General Electric's Military Jet Engine Group and AVCO's Systems Division. He received his Ph.D. from Case Western Reserve University in 1984. His current activities involve fluid mechanics-related models, including turbulence and transition modeling with applications to a broad range of flow regimes. He is the author or co-author of over 75 publications.
