Abstract
This report contains a description of the design and operation of an experimental appats for the analysis of two-phase flows similar to thom occuwring in boiler tubes at low pressures. Velocity and denuity profiles of air-water mixtures are determined across a passage in which boiling Ocditiosis are simulated by puping air through porous walls into a water strea. Photographs of the flow patterns are also presented as a qualitative check on the quantitative data. The results obtained are: 1) Vslocity and concentration profiles of the two phases for various values of the flow rates of each. 2) A classification of the flow into several patterns or regimes with quantitative data describing each regims. The data is suitable for use In acapering the physical phenen with athematical models and for developing a more accurate theoretical treatment of the flow of boiling fluids in heated channels.
