摘要：
The measurement of the two-phase flow rate is very important for the geothermal industry. Among the many different measurement techniques available, the orifice plate stands out for its simplicity, low cost, and the ability to provide real time measurements. Several data sets from different geothermal fields in New Zealand, Indonesia, and the Philippines are used to evaluate existing correlations all of which are based on homogenous flow models. Then derive and test a new correlation based on separated flow model with time discrete liquid phase flow for a more accurate measurement of two-phase flow in geothermal pipelines using the orifice plate. The new correlation is now being implemented successfully in New Zealand and other countries. (C) 2012 Elsevier Ltd. All rights reserved.
