...Yoshinobu Yamade; Chisachi Kato; Takahide Nagahara; Jun Matsui The origin, formation mechanism, and dynamics of suction vortices in a pump sump have been clarified by large eddy simulation (LES) applied to two different computational models. The first one is a pump-sump model with uniform flow...
