Comparaison de quelques caractéristiques de la turbulence mesurées dans divers écoulements d'eau en canal et en conduite
Comparison of turbulence characteristics measured in pipe and open-channel water flows
Ecole polytechnique fédérale de Zurich
Some turbulence characteristics which were determined in water flow through a rough pipe by hot-film anemometry  are compared with those obtained more recently by other authors using actual measuring techniques. It can be observed that the distributions of the turbulent intensities, the probability density of the fluctuating velocity, the eddy viscosity and of the Taylor microscales are generally in good agreement for pipe and open-channel water flows. Thus, the results of the rough pipe investigation  are confirmed.
