AIR-WATER PARALLEL CHANNELS TRANSIENT FLOW

ABSTRACT
Paper present results of the experimental and analytical study devoted to the investigation of transient regimes in air-water adiabatic two phase flow in the three parallel hydrodinamically not identical vertical channels. Under specific conditions in the individual channels, it is possible to obtain selfsustainable oscillations of the pressure drop which, due to inter-channel interactions lead to unstable flow regimes which are characterised with stable characteristics of the system as a whole and its individual channels. The onset of pressure drop oscillations in three parallel channel two phase flow in time and complex domain is analysed. Using experimentally determined transfer function of the system the criterion's for the determination of the linearity or nonlinearity was defined.
