The Forum "unsteady flows in turbomachinery" of ISROMAC16 mainly refers to unsteady flows in all kinds of turbomachinery
such as compressors, pumps, hydro turbines, wind turbines, turbochargers and so on. Internal flows in such turbomachinery has to be considered
as unsteady flows for investigation of loss mechanism, flow induced vibration, flow instability, cavitation. The purpose of this forum is to have
common basic knowledge concerning unsteady flows among these kinds of turbomachinery for better understanding of the complex phenomena. Many
computational and experimental techniques are used to clarify unsteady flows in turbomachinery, but it is important that appropriate numerical
model and experimental instrument has to be prepared to grasp a complicated unsteady flows. These technologies and common understanding should
be discussed in this forum.
The "Unsteady flows in turbomachinery" Forum of the ISROMAC16 Conference aims at providing opportunity for an exchange of studies as for recent research involving (1) behavior influenced by unsteady flows (2) experimental approaches (3) numerical approaches (4) design and optimization under unsteady flows (4) flow induced vibration. Any topics related unsteady flows in turbomachinery are welcomed.
