“…The flow was steady state, three dimensional and turbulent with the Re=10 5 . The initialized pressure was p=25 bar, while the temperature of dry air was T=298.15 K. Since grid sensitivity study was performed in previous research by authors [16,17,18] here the validation with experimental results obtained from literature [19] was done and presented in Table 2. Validation was done for simulation of flow through MHO without contamination, for 𝛽𝛽 = 0.7 and Re = 10 6 and as it can be seen from Figure 4, a good agreement was observed.…”

The influence of multi-hole orifice flow meter geometry parameters on the parameters of Newtonian fluid through multihole orifice meters was investigated using computational fluid dynamics as well as the effect of contamination in front of the MHO flow meter. The air flow was steady, three-dimensional, and turbulent. Analysed Newtonian fluid was air and physical properties that were considered were density and dynamic viscosity. The numerical method was finite volume method, and standard k-ε turbulence model was used for turbulence modelling. Multi-hole orifice meter with three different β parameters 0.55, 0.6 and 0.7, was observed and Reynold's number was 10 5 . The pressure drop and discharge coefficient were analysed. Numerical simulations were performed using commercial software the STAR-CCM+ 2019.2. It was found that increase in 𝛽𝛽 parameter results with the decrease in pressure drop and increase in discharge coefficient. Also, it was found that that the influence of 𝛽𝛽 parameter is much higher when analyzing pressure drop rather than discharge coefficient values. Numerical simulations were also performed to investigate the effect of contaminations in front of the MHO plate with 𝛽𝛽 = 0.5, on the discharge coefficients. It was found that as the contamination angle is increased the discharge coefficient tends to increase.
