Holocinematography for Studies of Turbulent Multiphase Flow

Abstract

The development of a high-speed holocinematography system for three- dimensional time-dependent measurements of the dynamics of dispersed flows is described. An on-line system based on a copper-vapor laser was assembled and used to obtain holocinematogram film strips of a particle-containing flow field. The present system can operate at framing rates up to 6000 holograms per second, yielding film strips up to 70 holograms long with a field of view having a diameter of 35 mm and a length of 120 mm. Extension to an off-axis configuration, for higher resolution also appears to be feasible. Either configuration provides unprecedented capabilities for studying laminar and turbulent single or multiphase flow phenomena that are not accessible using existing methods. (kr)
