PUMPSCHWINGUNGEN IN EINER LUFTTECHNISCHEN ANLAGE: VERGLEICH ZWEIER RECHENMODELLE ANHAND EXPERIMENTELLER ERGEBNISSE

Abstract

Air-flow installations composed of fluid machine, pipes, air-vessels and throttles are disposed towards press ure and mass-flow fluctuations at small mass flow rates. Computational models of lumped and distributed parameters both are suitable to the description of such dynamical behaviour as it has been proved by comparising with experimental results. The dynamical treatment of the fluid machine is of great importance within both models.
