abstract
An examination is made of two phase dispersed air bubble flow about a cylindrical conductor emitting a constant heat flux. The technique of Digital Pulsed Laser Velocimetry is utilized in order to obtain a full-field, non-invasive measurement of the resulting bubbly flow velocity field. Digital Pulsed Laser Velocimetry is a rapidly advancing flow visualization technique in which the instantaneous velocity profile of a given flow field can be determined by digitally recording tracer or seed images within the flow itself and then conducting a completely computational analysis of the data. Earlier studies utilizing the described technique have been carried out for numerous single phase flow systems. In this work results were obtained for a simple two phase system in order to demonstrate the effectiveness of the developed digital data acquisition and analysis methodologies which are unique among current systems of similar design.
