LIMITATIONS OF SPHERE ANEMOMETRY FOR LOW GAS VELOCITY MEASUREMENTS

LIMITATIONS OF SPHERE ANEMOMETRY FOR LOW GAS VELOCITY MEASUREMENTS

Sphere anemometry technique is re-visited for low gas velocity measurements during full-scale fire tests. This technique has the advantage of requiring only one channel per sphere for data acquisition, in addition to being cheap and rugged, The results indicate that the technique is useful for small fuel load burns with low radiation levels. For large fuel loads, the usefulness is up to sprinkler activation temperatures.
