• Dr. A. Hunter Fanney, Chief Building Environment Division   Particle Image Velocimetry (PIV)   BFRL researchers are using Particle Image Velocimetry to measure the air flow distribution through heat exchangers used in residential air conditioners. The data gathered from these measurements is used to validate CFD air distribution predictive models. Detailed knowledge of the air flow distribution is critical for the development of high-efficiency heat exchangers.
