Abstract
The velocity components of the high temperature high speed flow produced by a simulative device were diagnosed by single-line hydroxyl tagging velocimetry. The simulative device was driven by H2/air combustion gas, worked like a shock tube, held about 10-ms. The HTV tagging lines were put after the exit of device, and the experimental images at flow’s different regions were acquired through changing the tagging lines’ positions corresponding to the exit of device. And the velocity components along the device axis on tagging lines were calculated from the images. The results indicated that the velocity values of the flow in compress region were much slower than those in expansion region. Between the flow’s first expansion and compress regions, the velocity values at center were higher than those at both sides, but in the flow’s second expansion region, the velocity values at center were slower than that at both sides.
