Using CFD to Reveal Particle Concentrations in These Specialized Environments
Cleanrooms are critical spaces within many industries that are dedicated to uniquely sensitive processes or high-value products such as computer chips and lifesaving vaccines. They typically have very high air change rates related to the ISO rating class required for the processes they house. The various ISO classes represent the airborne particle concentrations allowed in the space and range from ISO 9 (the “dirtiest”) to ISO 1 (the “cleanest”).

Leveraging CFD Modeling in BESS Applications
As power grids evolve and become more modern and complex, battery energy storage systems are being used more frequently. Commonly known as a BESS, this device is typically used for power grid energy storage as an operating reserve, for demand-side load management and for frequency control, as well as to minimize the risk of power outages. It is often used as an energy storage solution with intermittent renewable energy sources.

Using CFD to Optimize Air-Change-Driven Labs
Labs use significant amounts of energy due to their makeup air requirements driven by the air changes needed to protect lab personnel from exposure to airborne hazards. There is currently a big push in the industry to improve energy efficiency and decarbonize lab facilities. One way to do this is to scrutinize air change rate requirements by relying less on established rules of thumb and more on analysis based on the unique needs of the facility.

A CFD Classroom Case Study
Obtaining efficient ventilation with overhead mixing systems for applications in heating climates can be a challenge. Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).
