Abstract
Measurements of bubble and liquid velocities in two-phase flow have be en made using a new forward/backward scattering Laser Doppler Velocime try (LDV) technique. A standard LDV fiber optic probe was used to meas ure the bubble velocity using direct backscattered light. A novel retr o-reflector and lens assembly permitted the same probe to measure the liquid velocity with direct forward-scattered light. Preliminary resul ts show the usefulness of the technique in a duct of narrow thickness dimension.
