“…Numerical simulations of fluid flow inside hydraulic valves are conducted for various goals, to investigate flow forces (Domagala, 2008;Lisowski et al, 2015;Lisowski et al, 2016;Lisowski et al, 2018) or to investigate dynamic behavior of valve components (Beune et al, 2012;Domagala, 2016).…”

“…In order to verify the applicability of the recommended valve, the flow characteristics of two fluids, superheated steam and hydrogen, under different valve opening was carried out. Lisowski and Filo (2016) analyzed the flow field through a proportional flow valve by CFD method for two types of spool opening, round and triangular. They analyzed the flow for the Reynolds number ranging from 500 to 4200, corresponding to transitional and partially turbulent flow.…”

Flow behavior through a gas turbine double-container fuel valve is numerically studied. Normally the gas fuel supply pressure of the gas turbine sites is over 20+ barg while the combustion chamber pressure is around 12 barg in base load operation and slightly more than atmospheric during start-up. Therefore, the flow control through this high range of pressure ratios is a very difficult and costly task with a single-container control valve. The double-container valve is an innovative design which consists of two parts, SRV (Stop Ratio Valve) followed by GCV (Gas Control Valve), in a compact unit. SRV maintains a significantly low pressure upstream of the GCV during gas turbine firing to establish flame and control fuel flow during acceleration. It opens the GCV to a position where it is much easier to control the flow through the valve. The same situation exists in base load operation when the turbine load is changing. The obtained results prove the special design of the valve to maintain linear characteristics of flow with stroke position in GCV. The results of the mass flow are given for various GCV stroke openings at various valve pressure ratios. Also, the range of pressure ratios for a proper operation of GCV is determined. SRV regulates the middle pressure between the two parts based on rotor speed. Therefore, a sensitive combination of globes position takes place during gas turbine operation.

“…One of the unknown factor during modelling of pressure control valve are flow forces which are difficult to evaluate or predict during fluid flow. There are, however, conducted research which allows to measure flow forces directly on the working components, but that has been made for fixed position of working components not during the fluid flow (Lisowski et al, 2016;Lisowski et al, 2018). Computer modelling tools allows also for simulating other causes of valve failures like erosion or cavitation which is presented in work (Domagala et al, 2018a) and (Domagala et al, 2018b).…”

Hydraulic power systems are widely used in heavy machinery. Safety of such a systems have a major importance due to the fact that any failure may cause environmental contamination or serious injury. One of the component which protects hydraulic drive systems against excessive rising of working pressure is a safety valve which aim is to maintain pressure in the systems below acceptable level. Pressure control valves which plays important role in a hydraulic systems may have very simple or complex structure. Even in case of the simplest structure of such valve modeling is not an easy task. The new quality in designing hydraulic valves bring CFD method and FSI (Fluid Structure Interaction) methods.
