EXPERIMENTAL INVESTIGATION OF THE APPEARANCE AND DEVELOPMENT OF TURBULENCE IN PIPES

It is shown that in laminar-turbulent transition there first appear therein clearly pronounced sinusoidal oscillations, the development of which subsequently leads to the formation of individual turbulent centers. The dependence of intermittance coefficient and number on Reynolds number is described comparatively well by an integral function and density function of normal error distribution law respectively. Investigations were conducted by the scattered-light method using a special hydraulic device of the closed type with a square- and round-section working part.
