Measurement of fluctuation characteristics of turbulent wakes
Abstract
A survey is presented of methods for the measurement of gas-density fluctuations in turbulent wakes of hypervelocity objects. It is shown that the performances of the luminous-point method and the schlieren method are better than the performance of contact methods.
