Experimental study of coagulation and sedimentation of gas-particle suspension in closed tube under transfer to the shock-wave regime

Abstract

The peculiarities of efficient coagulation and sedimentation of fine-dispersed gas-particle suspension are investigated experimentally at oscillations near the first eigenfrequency in a closed tube at transfer to the shock-wave regime under low excitement amplitudes. We obtain the temporal oscillograms of the gasparticle suspension pressure near the piston: in the resonance, the oscillograms are close to bursting but retain a continuous mode. The dependences are obtained for coagulation and sedimentation duration on the piston displacement amplitude and frequency.
