Contribution to report ``Critical flow phenomena in two-phase mixtures and their relationships to reactor safety`` (for Geneva conference)

Normally, in the flow of a flashing liquid through a pipe, it is assumed that the location of the choking phenomenon, if it exists, is at the exist of the pipe. Experiments have indicated that thee are circumstances under which choking can occur at the entrance instead. These experiments were performed to study the flashing of initially-compressed water through short lengths of pipe with length/diameter ratios of up to 20. Entrance configurations considered included sharp and rounded transition… more

Steam-Water Critical Flow From High Pressure Systems. Interim Report

In an earlier report, the problems associated with the prediction of the critical discharge rates of steam-water mixtures were discussed in detail. That report also gave the results of an experimental investigation of critical flows from long flow passages performed at low pressures. That investigation was later extended to consider short tubes, nozzles, and orifice flow configurations. The present work was undertaken to experimentally investigate the critical discharge phenomenon at higher pre… more
