Research on the Design Theory of Swirl Generator Attached to a New Bidirectional Flowmeter

Abstract

Based on the application of hydrodynamics, a new method of designing the swirl generator attached to a new bidirectional flowmeter is put forward. The 3-dimensions simulation in CFD is carried out to study the fluid motion for various amount of vanes attached to the swirl generator and various intake velocities. The results of simulation testify that the tangential velocity is linear proportional to radius according to the new design method for the swirl generator which can be used in a new bidirectional flowmeter. The simulation results also show the reverse flow exist s in lower intake velocity whereas increasing the amount of vanes attaching to the swirl generator will lessen the reverse flow. The method of simulation in 3-Dimensions model in this paper will be an example in fluid analysis. The 3-D fluid simulation for annular cylinder will do good to study the similar field. The results will be applied in designing the swirl generator and measuring the cubage flux by the new flowmeter.
