WebPart II: Heat Transfer 1 Heat Transfer with Phase Change Evaporators and Condensers Professor Faith Morrison Department of Chemical Engineering Michigan Technological University Heat Transfer with Phase Change So far we have discussed heat transfer at a boundary due to a temperature difference between bulk temperatures x bw q hT T A WebOct 1, 2004 · This study deals with the phase distribution of gas–liquid two-phase flows in a simulated plate heat exchanger with a single channel. Dynamic flow behaviors were visualized by the thermal neutron radiography method and the two-dimensional void fraction distributions were obtained via some image processing methods.
