Paper Abstract

By means of Hartmann Sensor at the rate of 419 Hz, a series of dynamic degraded wave front of collimated laser transport perpendicularly across a heated air flow was measured. The airflow was generated using a vertical-placed nozzle. An integral result of the airflow density distribution was educed. Both span-wise direction and stream-wise direction structure convection were observed. Some pilot study of flow field visualization was made.
