✦ Synopsis

Abswaet-Analysis

of the conservation equations of disperse two-phase Row reveals that the pressure gradient cannot reach infinity for critical flow conditions. Anew criterion of the critical Row conditions is suggested which agrees with experimental results. The critical velocity in disperse two-phase Row depends mainly on the density ratio of bolh phases and the particle concentration: the velocity of sound depends on the sound frequency in addition. Consequently, the velocity of sound can he higher or lower than the critical velocity.
