摘要
本文对钝头回转体垂直及斜出水流场采用TR-(Time-Resolved)PIV技术进行测量,并对斜出水流场进行3D-StereoPIV(三维体视PIV)测量。文中介绍了测试技术及测量结果,揭示了出水过程中流动结构及其演变,展示了TR-PIV技术对具有瞬态历程特征的出水流场研究的适应性。
2D and 3D Time-resolved PIV technique was used to measure flow field around vertical waterexit body and inclined water-exit body,respectively.Serial maps of velocity and vorticity with high time and space resolution was get. The experimental results revealed the complicated flow structure around waterexit body and its evolution, and also indicates the good adaptability of TR-PIV to investigation on the water-exit problem.
