Description...

Do you know that nearly all turbulence models cannot accurately predict properties both of boundary layers and free shear flows? Since virtually all practical turbulent flows contain both boundary layers and free shear regions, accuracy for both is needed to have a reasonable chance of making satisfactory engineering predictions. Do you know that the two most widely used turbulence models for incompressible and transonic flows are very innaccurate for supersonic and hypersonic flows? How confident can you be that such a model accurately represents effects of compressibility in the transonic regime? And, finally, do you know that a widely used turbulence model is not consistent with the law of the wall except in the special limiting case of a constant-pressure, incompressible boundary layer? Is it no wonder that this model fails for many applications?

These are examples of why most turbulence models are unsuitable for general applications and are limited to a small range of problems. In this course, you will learn that the failure to recognize this minimum requirement has impeded progress in turbulence modeling for the past 40 years. Developments of the past decade have finally overcome these fundamental shortcomings and have yielded major improvements in computational accuracy. That's the theme of this remarkable two-day course. Here you will:

• Gain an understanding of the strengths and limitations of turbulence modeling.
• Find out how to select a turbulence model that introduces minimum complexity yet still captures the essence of the relevant physics.
• Learn how to use simple analytical tools to enhance the physical foundation and accuracy of turbulence models.
• Discover the common sources of error and the limitations for all classes of models.
• Obtain complete details about Dr. Wilcox's new two-equation and stress-transport models that are accurate for both wall-bounded and free shear flows, including separated flows from incompressible to hypersonic speeds.

The course is based on the soon-to-be-released Third Edition of Turbulence Modeling for CFD, by David C. Wilcox. As with the text, the course has undergone major improvements and revisions, and represents the state of the art of this important branch of Computational Fluid Dynamics.

Who Should Attend...

Managers will learn what constitutes a suitable turbulence model for a given application and how to interact more effectively with specialists. Research engineers and programmers will discover the truths and myths of turbulence modeling as they acquire a systematic methodology for testing and validating turbulence models and associated software.

Key Topics...

The AIAA has sponsored this short course since 1994. Dr. Wilcox offers students the benefits and insights of his 40+ years of industrial experience in computational fluid dynamics, turbulence modeling, boundary-layer transition, hypersonics, and basic fluid mechanics. Dr. Wilcox has worked with McDonnell Douglas, TRW Systems, and Applied Theory, Inc. He founded DCW Industries, Inc. He has taught several fluid mechanics and applied mathematics courses at UCLA and USC. The following are comments from previous attendees of Dr. Wilcox's AIAA short courses:

• "An excellent overview of the current state of turbulence modeling. An equally excellent way to go from theory to application with a thorough understanding of the strengths and weaknesses of the models." Timothy Madden, National Academy of Sciences
• "Excellent speaker - able to keep your attention focused on the subject." Guy B. Spear, Atlantic Research Corp.
• "Excellent lecture!" Kenji Yoshida, Kawasaki Heavy Industries Ltd.
• "Dave's knowledge of the field was very impressive." Daniel Marcus, Lawrence Livermore National Lab

Miami, Florida. A list of hotels in the appropriate location will be included with your confirmation materials.
