TWO-PHASE GAS-LIQUID FLOW OSCILLATIONS: PRELIMINARY SURVEY,
Abstract
A review of a representative number of references for various types of two-phase gas-flow oscillations has been conducted. The principal conclusion is that at this time there is no reliable way to predict the onset of, magnitude of, frequency of, and disappearance of flow oscillations in two-phase flow systems. A consensus of the existing experimental results indicates that the tendency for a system to oscillate can be reduced by reducing the inlet subcooling, increasing the system pressure level, eliminating heated section exit restrictions, decreasing fluid level in a riser, if present, and increasing the flow restriction at the heated section inlet. In addition, it is believed that useful stability maps can be prepared that indicate regions of operation in which there will be no flow oscillations. For a given fluid system, the parameters necessary to determine this map are geometry, inlet subcooling, flow rate and heat flux. (Author)
