Investigation of the velocity relaxation of micron-sized particles in shock waves using laser radiation.
The differential Doppler method used for measuring flow velocities and velocity fluctuations calls for the presence of particles suspended in the flow which act as scattering centers. Experiments conducted with shock waves allowed us to investigate the behavior of these particles at very high accelerations. It would be shown that under normal conditions, particles 0.1-1 micro in diameter are capable of following within a few microseconds velocity variations in flows of at least 200 m/sec.
