Abstract

Experiments were performed within Rutgers University’s supersonic wind tunnel to study the effects of off-axis laser energy deposition on the flow field about an ogive-cylinder. In this experiment, the perturbation of the flow field was accomplished by using an infrared laser source, focused to a point ahead of the ogive-cylinder. Stereoscopic particle image velocimetry (SPIV) measurements were performed to quantify the effects of energy deposition on the flow field at discrete time delays following the generation of the spark. The SPIV results showed a measurable change in streamwise velocity about the ogive-cylinder, downstream of shock structure; in contrast, the spark was shown to have little influence on the vertical velocity component. Data corresponding to later times showed the passage of an induced jet through the flow field. The jet rotated about its axis as it convected, in agreement with previous qualitative imaging. These results demonstrate the feasibility of using SPIV to investigate the influence of laser energy deposition on the flow field.
