| Summary: | Knowledge of multiphase flow is essential for many industries and the vast majority of work on this topic has been done using pipes of 25-50 mm. However, developments in a number of industries, from heat exchangers to large diameter deep water risers need the knowledge to use larger diameter pipes, in which the behavior of multiphase flow may be different from that in smaller diameter pipes.
In the present study the experiments in vertical air/water two phase upflow were performed using a riser of 127 mm in diameter at different pressure to change the density of the gas. Data on void fraction were gained using a Wire Mesh Sensor (WMS). The data were analyzed to obtain flow patterns, frequency etc. Using these data comparison with different prediction methods was carried out. |
