| 摘要： | A new flow-visualization technique has been developed for use in the NASA Lewis Research Center's Icing Research Tunnel (IRT). This technique uses a sheet of light shining across the wind tunnel to illuminate a mist of water droplets in the air and display any organized flow patterns. Since the IRT already has the special water spray system required for aircraft icing experiments, no special visualization seeding material is required. The system has been used to visualize the changes in tip and leading edge vortices caused by ice accretion. Because the IRT's icing spray is used as part of the visualization technique, changes in the flow patterns about a wing can be observed and measured during the ice accretion process. |
