...Peixun Fang; Chuangxin He; Peng Wang; Sihua Xu; Yingzheng Liu The present work concentrates on the simulation enhancement of steam flow through a control valve using the data assimilation (DA) approach based on ensemble Kalman filter (EnKF). The k-ω shear stress transport (SST) model is used...

...Guillermo Palau-Salvador; Pablo González-Altozano; Jaime Arviza-Valverde The ability to understand and manage the performance of hydraulic control valves is important in many automatic and manual industrial processes. The use of computational fluid dynamics (CFD) aids in the design of such valves...

...Ryo Morita; Fumio Inada; Michitsugu Mori; Kenichi Tezuka; Yoshinobu Tsujimoto Under certain opening conditions (partial opening) of a steam control valve, the piping system in a power plant occasionally experiences large vibrations. To understand the valve instability that is responsible...
