Seminar 38 -- The Impact of Uncertainty and Validation Quality on CFD Results

This product contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

CFD is a powerful and efficient tool that provides scientific analysis and images to enhance the design. It is a practical and cost effective method to investigate different design alternatives especially in large industrial and commercial buildings. However, the CFD results should meet some level of accuracy to be used in design process. Some factors like the type of the CFD model, boundary condition set up, mesh dependency, and convergence criteria affect the uncertainty and accuracy. The speakers go through several different industrial applications to show the work flow and importance of uncertainty and validation quality in HVAC industry.
