As observed experimentally and numerically, the blade cavitation in a waterjet pump presents multi-temporal-spatial scales under the inlet guide vanes (IGVs) wake …
The paper performs an investigation on multi-scale coherent structures that exist in different flow patterns of triple interacting plumes. Time-averaged and turbulent flow characteristics …
The momentum transport and entrainment of a developing plane jet are dominated by coherent structures. Percipience about the formation, evolution, and interaction of these …

We propose a modified parallel-in-time—parareal—multi-level time integration method that, in contrast to previously proposed methods, employs a coarse solver based on a reduced …
In unshrouded turbine rotors, the tip leakage vortices develop and interact with the passage vortices. Such complex leakage flow causes the major loss in the turbine stage. Due to the …
