FLOW VISUALIZATION AT THE LIQUID FREE SURFACE

ABSTRACT

This article presents the methods used to visualize the laminar and turbulent free-surface liquid flow and to photograph the hydrodynamic spectra. The real images of laminar flows gave experimental evidence for the qualitative change of a viscous fluid flow for values of the Reynolds number Re = 1. The visual image of the turbulent flows has allowed an optimal geometric form design for fixed and moving bodies without boundary-layer separation.
