SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
A comparison of the performance of 54 void fraction correlations based on unbiased experimental data set of 3385 data points. A comprehensive literature search was undertaken for the available void fraction correlations and experimental void fraction data for upward and downward vertical and horizontal two-phase flows. The performance of the correlations in correctly predicting the diverse data set was evaluated. Comparisons between the correlations were made and appropriate recommendations were drawn. The analysis showed that most of the correlations developed are very restricted in terms of handling a wide variety of data sets. Based on this analysis void fraction correlations with the best predictive capability are highlighted.
Keywords:
Two-phase flow, void fraction, flow pattern, flow visualization, vertical and horizontal pipes.
