Abstract

To meet the requirement of unsteady flow rate generating system for compressible fluid, an inlet flow rate control method with sonic nozzle is proposed. When inlet flow rate is known, feedback of unsteady flow rate can be obtained by an isothermal tank. A proper sonic nozzle is designed according to the technical requirements, and the flow rate is calculated. Open loop experiments are carried out on generating system with and without sonic nozzle. The results indicate that influence of downstream on upstream can be greatly reduced by the designed sonic nozzle, and accurate feedback of unsteady flow rate is ensured.
