“…Among these devices, the orifices have been standardized and widely used for their advantages, such as simplicity in design, installation, and replacement; relatively low cost; and the absence of moving parts. However, they also have the disadvantages of high permanent pressure loss, sensitivity to incoming flow distortions, and nonlinearity (Shaaban, 2014). Compared with the standard orifice, the perforated plate (with multiple holes distributed on it) can balance the flow, introduce less turbulence, and reduce energy loss.…”

Abstract:The perforated plate is one of the effective devices for measuring flow rate accurately. In this study, a perforated plate is investigated for its characteristics, mainly including discharge coefficient C and pressure loss coefficient ζ, when applied to cryogenic fluids with the help of ANSYS Fluent. Three cryogenic fluids are studied, including liquid nitrogen (LN 2 ), liquid oxygen (LO 2 ), and liquid hydrogen (LH 2 ). For comparison, two states of water are also investigated. The realizable κ-ε model with standard wall function is used to describe the turbulence and simulate the near-wall flow. The Schnerr-Sauer cavitation model is used to investigate the effect of cavitation on the performance of the perforated plate. Simulation results indicate that the upper limit of Reynolds number of the perforated plate is significantly dependent on the properties of the measured fluid when the temperatures of the fluids are set as the normal boiling point temperatures and the outlet pressures are 0.2 MPa.

“…Results of the numerical simulations at different diffuser geometries were submitted to a genetic algorithm that estimated the optimum diffuser geometry according to the method described in [32]. The optimum diffuser geometry is the geometry that minimized the diffuser loss coefficient and hence maximized the diffuser pressure coefficient at the same diffuser's outlet width and radius.…”

“…This will add to the cost of the system. One of the major disadvantages of using orifice plates is that, as a result of energy loss due to turbulence in the fluid passing through the orifice, a permanent pressure drop may occur such that:

Δ P_{p} = Δ P_{i} (1 - 0.24 β - 0.52 β^{2} - 0.16 β^{3})

where ∆ P p is the pressure drop downstream of the plate, ∆ P i is the pressure drop across the orifice plate, and β is the ratio of the hole in the orifice plate and cross sectional areas of the pipe upstream (See Fig. ).…”

“…A burst travelling in the same direction as a moving cargo fluid will take a shorter time to move between the transmitter and the receiver than it would in static fluid, while a burst travelling against the direction of flow will take longer. When fluid temperature and density are known, manufacturers claim an accuracy of ±1% and other literature puts the figure at 0.5% for both liquid and gas . Where the transducers are external to the pipe signal attenuation due to air spaces, the use of a pipe liner can significantly decrease the accuracy of the flowmeter.…”

Review of flowmeters for carbon dioxide transport in CCS applications

et al. 2016

Carbon dioxide (CO2) emissions from power stations and industrial plants are seen as major contributors to what is known as the greenhouse gas (GHG) effect. Carbon dioxide capture and storage (CCS) is one technology which may reduce the quantity of CO2 released into the atmosphere but development of CCS has slowed due to the absence of a viable financial model. Metering technology is a prerequisite in enabling realistic financial decisions to be taken; however, there is currently a paucity of research into the types of flowmeters which would be suitable for incorporating into CCS transportation chains. This paper reviews and summarizes existing metering technologies with a view to establishing their suitability for measuring high mass flowrate, supercritical CO2. Open channel, differential pressure, velocity measurement, direct mass measurement, and electrical, magnetic, thermal, sonic, and radiation technologies are all considered. The challenges associated with each generic group are described, and recommendations made regarding the practicalities of using particular types of meter for CO2 transport in CCS applications. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd.
