The Fitting Formula of Outflow Coefficient for the V-Cone Flow Meter Based on FLUENT

The V-cone flow meter is widely used to measure gas, liquid and high temperature steam in current industrial production. By applying the FLUENT software of CFD, a three-dimensional model about the V-cone flow meter is built. The effect of technical parameters on flow in the V-cone flow meter field has been studied by using computational fluid dynamics (CFD). The data fitting for empirical formula of the outflow coefficient was completed by using MATLAB software to provide some basis for the further production and exploration. The simulation outflow coefficient is relevant to the parameter of the effective diameter ratio , the diameter of pipe D, front-cone angle and back-cone angle .

External Gear Pump

A three-dimensional model of an external gear pump and a new application of an algorithm for the measurement of the unsteady flow rate in hydraulic pipes are presented. The experimental delivery flow ripple was compared with the outcomes of a simulation under different operating conditions. A comprehensive computational fluid dynamics model of the pump and of the high-pressure delivery circuit was developed in SimericsMP+®. The pump model considers the clearances, which vary according to the shaft angle, between the tip of the tooth and the inner surface of the stator, as well as between the flanks of the teeth that are in contact. The pump delivery circuit is constituted by a straight pipe with a fixed orifice at the end to generate the load. The model of the entire system was preliminarily validated in terms of delivery pressure ripple. Subsequently, the simulated flow ripple was contrasted with the instantaneous flow rate, measured by means of an innovative flow meter. It was found that the proposed flow meter is reliable in assessing the flow oscillations under the various working conditions.
