Seminar 78 -- Work Smarter Not Harder: 3D CFD Not Required!

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.

This session aims to highlight smart indoor environmental modeling approaches. With the advances in computational and storage resources, it appears a 3D modeling is the first starting point to model indoor environments. However, a 3D modeling approach may not be the best solution to understand the underlying airflow and thermal mechanisms in indoor environments. Therefore, this session will demonstrate computational cost effective real-world case solutions to (i) model a building for natural ventilation, (ii) evaluate a gas turbine enclosure cooling system eductor, (iii) demonstrate cross ventilation, and (iv) estimate SARS-CoV-2 airborne transmission risks in buildings.
