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
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 speakers 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.
