Abstract: In the study on gas-liquid mixed flow technology, because of lack of common softwares in data management, process and analysis for gas-liquid mixed flow pipeline, many vitally valuble experimental data can not be supervised properly, the availability is relatively low and it is easier to drop-out. Therefor, it is necessary to establish a database for gas-liquid mixed flow pipeline. Meanwhile, an application software has to be programmed in order to retrieval the main technological and operational parameters of gas-liquid mixed flow pipelines at home and abroad, and still further, the comparison as well as error analysis of the results obtained from equations with those parameters (measured results) must be made to select an optimal equation in calculating pressure drop and liquid holdup to provide a basis for studying and designing the gas-liquid mixed flow pipeline.
