PIV for CFD Model Validation Benchmark Experiments: E201 Ocean Engineering Seminar

Seminar | February 14 | 2:30-4 p.m. | 3110 Etcheverry Hall

 Professor Barton L. Smith, Utah State University

 Department of Mechanical Engineering (ME)

Abstract: Before Computational Fluid Dynamics can be used for decision making, the uncertainty of the calculations must be found. To quantify the uncertainty of the calculations, the solution must be “Validated” against experimental data. While it may be tempting to use experimental results found in published literature for validation, such a practice can lead to unacceptable uncertainties because the values of important model inputs are typically not included in journal articles. Particle Image Velocimetry (PIV) is an excellent fluid velocity measurement technique for validation experiments since it provides high resolution and is unobtrusive.

In this talk, we will discuss some of the unique aspects of CFD validation experiments based on the literature and the speaker’s recent experiences. We will begin by discussing the validation process, then distinguishing validation experiments from traditional experiments. The unique features, benefits, and requirements of validation experiments will then be discussed.

Biography: Professor Barton Smith received his BSME from Michigan State University in 1990 and his PhD in ME from Georgia Tech in 1999. After a post-doc at Los Alamos National Laboratory, he joined the faculty of Utah State University in 2001. His research specializes in measurement uncertainty, CFD Validation Benchmark Experiments and Baseball Aerodynamics. He is the author of the website www.baseballaero.com.
