Competitive electricity prices and reduced profit margins have forced hydraulic turbines to
operate under critical conditions. The demand for extended operating ranges and the high …

Hydraulic turbines include stationary and rotating components. The interaction of the
components, mainly between the runner blades and distributor vanes, is critical when the …

A simple nondimensional model to describe the flutter onset of labyrinth seals is presented.
The linearized mass and momentum integral equations for a control volume which …

A labyrinth seal is commonly used to decrease the flow leakage loss between rotating and
static components in aero engines. It is susceptible to aeroelastic instability because of its …

A three-dimensional (3D) inner surface inspection system is developed in this research
based on circle-structured light, which is an improved laser triangulation method. A conical …

The dimensionless model presented in part I of the corresponding paper to describe the
flutter onset of two-fin rotating seals is exploited to extract valuable engineering trends with …

A fluid–structure interaction (FSI) model of a left anterior descending (LAD) coronary artery
was developed, incorporating transient blood flow, cyclic bending motion of the artery, and …

The paper critically reviews the current state of the art in flow inside sidewall gaps of
hydraulic pumps and turbines. It describes the consequences of the presence of this type of …

Concussions are among the most common injuries sustained by goaltenders. Concussive
injuries are characterized by impairment to neurological function which can affect many …

Labyrinth seal flutter is a critical phenomenon in turbomachinery, as it can lead to severe
structural vibrations and potential component damage. Accurate prediction and mitigation of …
