摘要：

A new technique using a gas laser has been developed to measure the void fraction, the liquid velocity, and its turbulence intensity in two-phase dispersed flows, especially in bubbly flows. An equation giving the relation between the laser beam transmission rate and the void fraction was deduced theoretically and confirmed experimentally on the assumption that the bubble size distribution is given.
