A Model for a Spool Piece made up of Venturi and Void fraction Flow Meter in Horizontal Flow

摘要

The analysis of the signals and the developed model of the SP, made up of VFM and WMS, has allowed the estimation of the mass flow rate of the phases in a air-water horizontal flow with a good accuracy in a large range of flow quality. The mass flow rate has been estimated with an error lower than 10% in the 73.3% of the cases. Moreover, the estimation error is considerably lower for the flow characterized by high values of quality and void fraction. In this range, where the experimental facility SPES3 will operate, the error in the mass flow rate estimation is always lower than 10% and 20% for water and air respectively.
