  • 0201 Stereo PIV measurement and wall pressure measurement of the pipe flow with semicircular orifice

説明

Experimental study on the turbulent flow in a circular pipe with a semi-circular orifice has been conducted. The velocity was measured by a stereo PIV system that provided the three components of mean velocity as well as streamwise vorticity on the cross section of the pipe at different streamwise locations. The distributions of mean vorticity exhibited symmetry about y-axis. Wall pressure measurement has been conducted along the pipe wall. The profiles of pressure fluctuations and cross correlation was obtained.
