Multi-objective optimisation of K-shape notch multi-way spool valve using CFD analysis, discharge area parameter model, and NSGA-II algorithm
Multi-way spool valves (MWSVs) with K-shape notches (KSNs) provide advantages such as improvement of the actuator speed control, micro-action, and response performance.However, the pressure drop (PD) associated with the energy consumption is larger of MWSVs under the high-pressure and large-flow condition.Meanwhile, extremely complex flow coefficie
