“…Similarly, flow-induced noise analysis for natural gas manifolds is conducted by the LES and FW-H hybrid method. 14 Zhang et al 15 researched the flow field to reflect noise generation mechanism by the CFD method, and the hydrodynamic noise is mainly caused by Reynolds stress in the jet transition zone and flow field vortex. Boersma 16 conducted simulation flow and acoustic field of a turbulent round jet with the help of LES and FW-H.…”

Two-stage sleeve control valve has been widely implemented in high-pressure difference hydraulic system, whose function is to reduce hydrodynamic noise. The sleeve with orifices plays a significant role in reducing the hydrodynamic noise. The ratio of orifices diameter between outer sleeve and inner sleeve, Ri is investigated in this paper. The coupling effect of Ri on the flow field and hydrodynamic noise is analyzed deeply by URANS and FW-H model. Furthermore, the pressure, velocity, turbulent kinetic energy and sound pressure level of the flow field are monitored. The results indicate that higher Ri will restrict the flow velocity in the orifices, and the distributed pressure drop of two sleeves will be even. The velocity of flow in the outer sleeve reduces from 130 m/s to 90m/s with the increase of Ri. In addition, larger Ri can reduce the hydrodynamic noise and obtain higher flow capacity. When the Ri is 1.2, the sound power level distributes evenly in the gap, and the radiation intensity of the sound source is the smallest. The study can provide a reference for the design of sleeves in high-pressure control valves.

“…However, an insufficient description of the control system for the contours of the metered supply of chemical agents does not make it possible to use the proposed method on other technological systems [7]. It is the solution of complex problems of theoretical and physical modeling of control systems in conjunction with shut-off devices, as noted by the authors of [8], is a relevant area in the development of drive synergy with elements of pipeline fittings.…”

This paper reports the new design of an experimental bench to study the effectiveness of the positional drive control system of shut-off fittings. For research, the operating modes of the disk flap and ball valve, based on proportional elements with feedback (4–20 mA), were programmatically formed and described. The mathematical model of control over shut-off devices has been analytically described on the example of a disk rotary valve with the possibility of further analysis of individual stages in accordance with the accepted assumptions. The operating control signal is justified with a serial asynchronous interface with an offset operating range of permissible values of –16.0 mA. Separate stages in the operation of the synthesized shut-off fittings based on accepted assumptions have been described. Measurements were performed for disc damper angles of 30°, 60°, 90° by variable value of the pressure control signal (1...4 bar) with sampling of measuring indicators for the control system in real time. The results obtained experimentally confirmed the adequacy of numerical modeling regarding the study of the disk rotary inter-flange valve, as well as preliminary assumptions in the mathematical model. Data were obtained to test the efficiency of controlled shut-off fittings (V-shaped ball valve, disc rotary inter-flange valve) at a sugar factory. The average angle of rotation for a ball is 17.61 degrees; the average value of the vapor temperature after cooling is 130.91 °C (subject to a given value of 130.0 °C). The deviation of the set value is 0.7 %. The average value for the angle of rotation of the disc damper at 43.0 degrees showed the largest deviation of technological parameters of 1.45 %.

“…As the valve opening decreases, the whole SPL of the valve becomes strong and exhibits dipole characteristics. Zhang et al [14] built a cavity model to verify LES and Lighthill's acoustic analogy hybrid method before computing the flow-induced noise of a threedimensional pipeline. Wang et al [23] also used the LES and Lighthill acoustic analogy to investigate the hydrodynamic noise of an underwater vehicle.…”

The flow-induced noise occurring in the prestage of the deflector jet servo valve (DJV) significantly affects the performance of DJV, which is a critical issue for electrohydraulic servo valves. To capture the root causes of flow-induced noise, DJV is numerically studied using computational aeroacoustics (CAA) methods in this paper. The acoustic field is investigated with Lighthill’s acoustic analogy based on the pulsation data from a large eddy simulation (LES). The flow-induced noise generation mechanism in DJV is revealed by analyzing the sound pressure level and vorticity distribution at different moments. Moreover, a kind of oscillation cavity model based on the Helmholtz oscillator is built, which reveals that the flow-induced noise is caused by self-excited oscillation and vortex. In addition, the result shows that continuous broadband dipole noise with medium- and high-frequency components of 1100 Hz and 2501 Hz dominates the DJV flow field. In order to avoid unexpected resonance, the natural frequency of the prestage should not coincide with the frequency of the flow oscillation frequency. Thus, this work can benefit the design and optimization of the prestage structure.
