Abstract

The flow field through Y-branch (θ=60°) of square channel is measured using multi-point LDV system and characteristic of split flow is discussed by comparison with T-branch of square channel. A mean velocity vectors indicates the difference of the shape of separated bubble and position of accelerated flow. A reattachment length is longer than T-branch of it and movement of reattachment point and frequency of movement is similar tendency.
