“…Інші автори у своїх дослідженнях використовують порівняльний аналіз чисельних і натурних експериментів [6] для вивчення впливу ефекту в'язкості на характеристики ТВПВ, зокрема на градуювальний коефіцієнт. В деяких випадках CFD технології використовували для прогнозування поведінки метрологічних характеристик ТВПВ [7] та їхньої оптимізації [8]. Чисельні експерименти імітують реальні експерименти з ТВПВ.…”

“…Some studies have validated CFD techniques to simulate the operation of water meters [16,25] and correspondingly, the influence of hydraulic fittings [8,26] or other structures [27] on the distortion of the measured flow. The use of CFD numerical models can effectively reduce the high cost of experimental testing with turbine flowmeters [28].…”

One of the unknowns in the instrumentation for water measurement is what degree of influence other hydraulic elements exert on the velocity profile and, consequently, on the measurement errors. In this work, the measurement errors of a horizontal-axis Woltman meter produced by a gate valve and by a butterfly valve in different hydraulic configurations were studied using a simplified numerical model. The gate valve was installed beside the meter and three pipe diameters upstream of the meter and were operated with closures of 75%, 50% and 25%, while the butterfly valve was installed at three pipe diameters upstream of the meter with closures of 0 • (open) and 30 • . The numerical model based on the rotor's torque balance equations and Computational Fluid Dynamics (CFD) was validated by experimental tests. According to the results, it was concluded that the proposed model is valid and capable of estimating the errors caused by the hydraulic fittings arranged next to the meter. In addition, it is evident that for the analysed operating range, both valves must be installed at least three diameters of straight pipe upstream of the meter.

The measurement lower limit of traditional turbine flowmeter is too large to satisfy the measurement requirements of small flow rate. A modified optical fiber turbine flowmeter based on the traditional turbine flowmeter principle was purposed. The front guide vane was specially designed with a helix angle to reduce the measurement lower limit and improve the measurement sensitivity. The theoretical model for the modified flowmeter was established based on planar vector triangle of flow velocities. From theoretical analysis, the conclusion that if the helix angle of front guide vane plus the helix angle of turbine equals to 90°, the starting volume flow rate of turbine can get minimum value and the sensitivity of the flowmeter can get maximum value was found. The correctness of the conclusion was verified by the Computational Fluid Dynamics (CFD) simulation.
