A NOVEL FLYING HOT-WIRE SYSTEM

A new flying hot-wire system has been developed for the measurement of highly turbulent and reversing flows. The apparatus is of rectilinear design, incorporating many features which extend its range of applica tion beyond the range of previous designs. One of the advantages of th is system is that it is mounted on a flow visualization wind tunnel wh ich allows complementary qualitative and quantitative studies to be pe rformed. This system has been used successfully to measure turbulent a nd reversing flows including the flow past a fence. Some results are p resented.
