Abstract:
The rear pressure measurement position of V-cone flowmeter is in the complex vortex structure area after fluid around the cone. The non-uniformity of the fluid field will influence the measurement precision of V-cone flowmeter. Large eddy simulation (LES) has been used to study the V-cone flowmeter’s 3-D flow field structure with different Reynolds number in this paper. The better fluid area information can gain by this way. The results show that the values of discharge coefficient (Cd) obtained from LES are more close to the experiment data than the values obtained from k-ε model. Different turbulence intensity with different Reynolds number effects the velocity distribution in the V-cone flowmeter’s flow field. When Reynolds number equals to 20000, the flow field within 8d distance from V-cone tail should keep from being disturbed while the flowmeter under working condition. The non-interfering distance from V-cone tail flow field increases with the Reynolds number raising. These analysis results can offer optimizational information for V-cone flowmeter performance and testing method improvement.

Abstract:
This article aims to improve the accuracy of gas flow measurement of cone flowmeter and get a high-precision expansibility factor calculation model with wide applicable pressure range and different upstream side pressure. The experimental research was based on the DN50 and DN100 two sets of V-Cone flowmeter designed by Tianjin University. As the standard gas flow facility by means of critical flow venturi nozzles was insufficient supply capacity and poor pressure stability in positive pressure method, the experimental data obtained from standard gas flow facility by using negative pressure method was used to fit out the V-Cone flowmeter expansibility factor calculation model --TJU-2012 model. The model was tested with the experimental data obtained from the standard gas flow facility and compared with other four cone flowmeter expansibility factor calculation models, its maximum relative error was better than 0.9% and square averaged root error was better than 0.6%, both of them are the least.

Abstract:
CO2 injection is an effective method for exploitation of natural gas hydrate. The injected CO2 flow measurement at inlet of wellhead is a gas-liquid two-phase flow for the exploitation of natural gas hydrate. The numerical simulation of gas-liquid two-phase flow is carried by FLUENT software in combination with a V-cone flowmeter. The rate of flow of fluid and the turbulent kinetic energy were analyzed for V-cone flowmeter. The efflux coefficients of V-cone flowmeter are calculated for the different equivalent diameter ratio. Based on homogeneous flow model, thoughts of James and the curves of volume flow, the lasted modified model of gas-liquid two-phase flow is obtained. The relative error is only 0.35%. It is feasible to measure the flow of gas-liquid two-phase flow by the lasted modified model, which will improve the exploitation of natural gas hydrate.

Abstract:
Abstract In order to solve the dilemma between the smaller pressure loss and the larger flow measurement signal in traditional throttle flowmeters, a throttle structure with the inner-outer tube was designed and analyzed. The mathematical relationship model deduced from hydrodynamics showed there were three major parameters to determine the designed throttle structure. Furthermore, the optimal results were achieved by combining orthogonal test design and computational fluid dynamics by taking the ratio of differential pressure of inner-outer tube divided by that of anterior-posterior tube as the optimization goal. Finally, the simulation results with the best level parameters showed that the differential pressure of the anterior-posterior throttle could remain not only the smaller value among other parameters with the same structure of inner-outer tube. On the other hand, it was about one order magnitude less than differential pressure of V-cone flowmeter in the similar installation conditions with the flow velocity varying from 0.5 to 3.0 m/s. The designed inner-outer tube flowmeter can not only save manufacture costs, but also avoid the large sensitivity of pressure sensors, which may lead to a broader application in chemical and petrochemical enterprises.

Abstract:
In order to study the mechanism of gas-liquid two-phase flow, a method of characteristic variables extracting based on Adaptive Optimal-Kernel (AOK) theory was represented in the paper. First, to collect dynamic differential pressure signal of gas-liquid two-phase flow through a horizontal V-cone flow meter, and then the AOK theory was used to analyze the dynamic differential pressure signal. The movement law of two-phase flow was discussed through the time-frequency spectrum. Finally, four characteristic variables were defined by using the time-frequency spectrum and the ridge of AOK. After the characteristic variables were visual analyzed, the relationship between the different combination of characteristic variables and the flow pattern was obtained. The results show that, characteristic variables defined by this method can get a clear description of the flow information. This method provides a new way for the flow patterns identification.
