PIV and LDV measurements at a smoke detector

The response behaviour of smoke detectors was optimized by means of quantitative flow measurements. These measured the incident and inner flows through the device under defined conditions with a standard fire in a fire test laboratory. While the PIV measurements took place in different planes outside the smoke detector, LDV was used to get exact point wise flow information within the confined space of the detector itself.
