Seminar 62 -- RANS vs LES: Modeling Airflow in Built Environment

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

RANS (Reynolds-averaged Navier-Stokes) and LES (Large Eddy Simulation) are two most popular computational fluid dynamics methods in modeling airflows for built environment. To help users decide which approach to be used in their applications, this seminar illustrates their pros and cons via various examples.
