“…The inclusive converging cone angle used was 21° (or a half angle of 10.5°) and the diverging cone angle used was 15° (or a half angle of 7.5°). Sharp, Johnson, and Barfuss (2018) showed that CFD can closely match the trends of laboratory data for different sizes of the ASME classical Venturi design. Other work done at the UWRL by the authors with a 48‐ and 52‐in.…”

Venturi flowmeter performance installed downstream of the branch of a tee junction

Venturi flowmeters are robust and can function in many different and difficult installations. One such installation is downstream on the branch of a tee junction. For the most accurate flow measurement, a Venturi in this installation needs a laboratory calibration. Laboratory calibration adds cost to a project, may not be feasible, and in some circumstances, the Venturi has already been installed and cannot be taken out for calibration. For these reasons, this research used computational fluid dynamics (CFD) to determine the percent difference from the manufacturer's straight‐line calibrated or expected discharge coefficient, C, and adjust for it in tee installations. Laboratory data were collected to validate CFD models. The Cs from tee installations, of different distances downstream of the tee branch, were divided by a corresponding straight‐line C at the same Reynolds number to create a ratio to adjust the straight‐line C for a more accurate determination of the flow rate.

“…Venturi showed agreement between the two Venturi sizes to within 0.6% in a straight‐line test setup. On the basis of the results of Sharp et al (2018) and authors' experience, physical laboratory data were not performed for the 24‐in. classical Venturi, considering the physics models calibrated for the 6‐in.…”

“…This study considered the parameters Y + and GCI (Grid Convergence Index) to ensure accurate computational results. For low Reynolds numbers, a target Y + ≤ 5 was adopted, as recommended by Sharp et al [ 23 ] and Versteeg and Malalasekera [ 32 ]. Conversely, for higher Reynolds numbers, specifically at 10,000,000, a Y + ≤ 300 was deemed acceptable, aligning with the recommended values for the k-omega-SST turbulence model [ 33 ].…”

“…[ 20 ]). Recent studies suggest a range of β-ratios between 0.2 and 0.8 to reduce the energy loss [ 22 , 23 ]. Furthermore, these studies identify acceptable θ d between 7° and 15° to lower energy loss, which is sensitive to small changes in the recovery cone angle [ 23 ].…”

“…Studying the influences of geometric parameters such as convergent cone angle, divergent cone angle, beta ratio, and throat length on pressure drop, [9] found that beta ratio was the most significant parameter. [10] Have studied CFD and laboratory data to determine the relationship between the classical Venturi meter design's recovery cone angle and associated head loss. As a result, the beta ratio and Reynolds number determine the best recovery cone angle for minimising head loss.…”

This study investigates the influence of turbulent parameters on the characteristic centreline of a fluid flow through a T-junction connected to a Vinturi tube through a pipe. Continuity equation, Momentum equation, and Energy equation of water are modelled and solved by using the ANSYS FLUENT 2020R1 Software free Demo. While the turbulent model with standard (k-ε) type is used to compute the turbulent parameters such as turbulent kinetic energy and turbulent dissipation rate for a pipe inner diameter of (D =25 mm) with a length from the T-junction centre line and at the outlet of the Venturi meter is (350 mm). The Reynolds number variation ranged from (1x10 4 to 3x10 4 ) at the step of (5000). The water flowing is considered in an x-direction flow to show the effects of the above parameters. The model is obtained on the velocity distribution, pressure drop distribution, turbulent kinetic energy, and turbulent dissipation rate. The results showed a discrepancy in the values of the effect of the T-junction on the Venturi meter concerning the velocity distribution and pressure drop, while they showed similar behaviour for the turbulence parameters.
