Popis: | The possibilities of speckle photography for determination of the characteristics of turbulence for gas-dynamic flows are analyzed. It is shown that by using two-exposure speckle photography, the energy spectrum and the scales of turbulence can be calculated, while one-exposure speckle photography provides information on the energy and anisotropy of turbulent pulsations. |
