WebJul 10, 2010 · Two-phase flow in a vertical tube tends to be more symmetric, since gravity acts equally in the circumferential directions. The gravitational force plays a more dominant role in the liquid phase – and … Webgeometric distributions orflow patterns thatareobservedincommonmulti-phase flows. This chapter describes the flow patterns observed in horizontal and vertical pipes and identifies a number of the instabilities that lead to transition from one flow pattern to another. 7.2 TOPOLOGIES OF MULTIPHASE FLOW 7.2.1 Multiphase flow patterns
WebIn most cases, the multi-phase flow correlations are based on the flow regimes that we have already discussed. For use in a multi-phase flow correlation, these flow regimes are plotted as Flow Pattern Maps. … Web服务热线： 4008-161-200 800-990-8900. 国家科技图书文献中心. © Copyright(C)2024 NSTL.All Rights Reserved 版权所有
