Abstract
LDV measurements were conducted in the turbulent round jet issuing into a counterflowing uniform stream for velocity-ratios from 0.8 to 7. Similarity of flow fields for the velocity-ratio 5 was confirmed for the jets with diameters of 10mm and 30mm. Also, confirmed was the linear dependence of the penetrating length of the jet into the counterflowing stream over various conditions investigated. Flow pattern is affected by the nozzle shape for velocity-ratios smaller than 1.3. The non-dimensionalized dividing streamline tend to be more slender and pointed with increasing velocity-ratio.
