“…As far as the moving grids in ANSYS CFX is concerned, the structural grids must be generated to ensure no element in constructed with a negative volume/poor quality shape occurs at each iteration while the valve disc is moving. To this end, the DDM successfully applied in previous work by the authors [21] is utilized. The previous work is extended by decomposing the whole domain into 4 sub-domains which now include the pressure vessel, connection pipe between valve and vessel, central domain of valve and the valve vent.…”

“…These simulations revealed a rich variety of flow phenomena such as secondary patterns, hydrodynamic instabilities, turbulent pressure fluctuations due to vortex shedding, etc. Meanwhile, many researchers started to apply CFD method in the design and analyze other types of valves like hydraulic control valves and servo valves [17][18][19][20][21]. For instance, Lisowski and Rajda [20] investigated the pressure loss during flow by hydraulic directional control valve constructed from logic valves.…”

“…The undertaken matter is focused on a spool type directional control valve with pilot operated check valves. Then, they proposed calculation of the forces associated with the flow using 3D CFD modeling [21]. The force values obtained in the CFD calculations were compared with those obtained on the test bench.…”

“…All of these studies were focused mainly on the direct influence of flow-induced vibration on internal structures; while relatively little attention has been given to indirect effects such as the impact of internal structures on the pressurized water reactor (PWR). The dynamic mesh model can be applied to determine the dynamic properties of the internal structures, as evidenced by several previous studies-many prior researchers have utilized this technique to simulate the dynamic properties of various types of fluid machineries such as valves, [11][12][13][14][15][16][17] pumps, 18,19 and more. These previous works suggest that the dynamic mesh model is well suited to analysis of a hypothetical drop accident in a PWR.…”

In this study, we conducted a simulation investigation of a hypothetical core barrel assembly drop accident based on the dynamic mesh model. The investigation included three separate circumstances: high-temperature dynamic water, hightemperature still water, and low-temperature still water. Results showed that dynamic parameters (e.g. velocity and resultant force) of the drop assembly in high-temperature dynamic water are smaller than those in still water due to the buffer effect of the flowing water. The velocity and hydraulic force in the dynamic water situation increased quickly at first and then remained stable throughout the remainder of the experiment; due to turbulence effect, the hydraulic force fluctuated slightly, first increased, then decreased, and then reached as stable a level in still water as that in dynamic water. The velocity of the drop assembly showed parabolic growth.

“…Recently there has been many research works concerning the flow analysis [8,16,18,19,[21][22][23][24][25][26][27][28][29][30][31][32][33], optimization of working medium flow and different types of valves. Programs based on Computational Fluid Dynamics allowing to conduct computer simulations, which reflect the nature of the physical phenomena quite well, are becoming increasingly important.…”

Abstract. The work includes a study on the comparative analysis of two test methods. The first methodnumerical method, consists in determining the flow characteristics with the use of ANSYS CFX. A modeled poppet directional valve 3/2 3D CAD software -SolidWorks was used for this purpose. Based on the solid model that was developed, simulation studies of the air flow through the way valve in the software for computational fluid dynamics Ansys CFX were conducted. The second method -experimental, entailed conducting tests on a specially constructed test stand. The comparison of the test results obtained on the basis of both methods made it possible to determine the cross-correlation. High compatibility of the results confirms the usefulness of the numerical procedures. Thus, they might serve to determine the flow characteristics of directional valves as an alternative to a costly and time-consuming test stand.
