Optimizing Design of the Guide-Vane Attached to the New Bidirectional Flowmeter

Article Preview

Abstract:

Performances of vanes with various numbers and front oriented-body with different shapes such as half sphere, half ellipsoid and cone are simulated by RNG κ-ε model and standard wall functions method in order to optimize the parameters of the front oriented-body attached on the new bidirectional flowmeter. The performances of weakening-vortex and the pressure losses attaching to various models are analyzed and compared with each other. The results show that the structure with cone guide-head and 6 vanes can obtain the minimum range of flow pulsation, the least pressure loss and the least reverse flow. The simulation methods and results will be used for reference to analyze the similar annular flow and design the steady device.
