| Summary: | 碩士 === 淡江大學 === 水資源及環境工程所 === 82 === Measurements of distribution of air concentration in
aerated flows are presented in this paper. The experiments
were conducted by applying constant temperature hot-film
anemometer and conical hot-film probe in a rectangular
channel at various slopes and discharge. The determination of
air concentration depends on classifying the meeasured
voltages into the catagory of water or of air. The 99.99%
lower limit of the velocity of water, assuming normally
distributed, is identified as the critical voltage which
classifies the output signals into one of the catagories of
water and air bubble.
