The Momentum flux in two-phase flow
The average momentum flux at a section of a pipe with twophase upflow has been measured by the impulse technique. Steamwater and air-water mixtures were tested in one-inch and onehalf inch nominal pipes. Homogeneous velocities ranging from 150 to 1200 ft/sec. and qualities from 5% to 85% were tested...

| Summary: | The average momentum flux at a section of a pipe with twophase upflow has been measured by the impulse technique. Steamwater and air-water mixtures were tested in one-inch and onehalf inch nominal pipes. Homogeneous velocities ranging from 150 to 1200 ft/sec. and qualities from 5% to 85% were tested. The results are compared to the results of models currently in practice for predicting pressure drop and critical flow. The influence of the void fraction, the velocity profile, phase distribution and fluctuations upon the momentum flux are discussed. |
