Measurement Of Velocity Distribution For Flow Through A Bileaflet Valve Using Color-Coded Digital Particle Tracking Velocimetry, Tienfuan Kerh, Yen-Ming Chen, I Tsou
Journal of Marine Science and Technology
An experimental method, the so-called color-coded Digital Particle Tracking Velocimetry system was set up in this study to investigate viscous flow through an artificial bileaflet valve with three different opening angles, 5°, 30°, and 45°, respectively. An oscilloscope that generated stable wave speed was taken to calibrate measuring result of the equipment. Besides, a fully developed pipe flow case was used to check the reliability of experimental system, and a statistical t-test was performed to further enhance the comparison of analytical solution and measurement. From the details of randomly distributed velocities, interpolated velocity components, and velocity profiles for the studied …
