High-speed Rotary On/Off Valve

This purpose of this project is to investigate the flow characteristics inside a novel high-speed rotary on/off valve. The researchers have investigated stationary and rotary states of the valve. The valve was decomposed into sleeve donut, spool center section, spool outlet turbine, and each section was simulated in FLUENT separately. CFD results on pressure drop across the spool were compared with the experimental results, and they were consistent. The researchers also use CFD to verify the analytical relationship between reaction torque and valve rotary speed. Currently, they are using the CFD technique to simulate different spool and sleeve configurations for our next valve generation.
