Simulating unsteady turbulent flow in turbomachines is still challenging due to the
complexity of blade geometry and relative motion between rotor and stator. This study …

In this paper, the effect of aerodynamic asymmetries on the flutter characteristics of
turbomachinery blades is investigated. Specifically, the present method is used to study the …

High speed rotating blades are crucial components of modern large aircraft engines. The
rotating blades under working condition frequently suffer from the aerodynamic, elastic and …

This paper investigates how the natural frequencies of planetary gears tend to gather into
clusters (or groups). This behavior is observed experimentally and analyzed in further detail …

Accurate prediction of plantar shear stress and internal stress in the soft tissue layers of the
foot using finite element models would provide valuable insight into the mechanical etiology …

Assembly interface of aircraft vertical tail is a large thin-wall structure and made from titanium
alloys, which causes easily machining vibration, deformation and undercutting in finish …

A generalized flat plate cascade model is developed in this study to predict the unsteady
aerodynamics of a blade row with circumferentially nonuniform spacing in subsonic …

Most of the existing mistuning research assumes that the aerodynamic forces on each of the
blades are identical except for an interblade phase angle shift. In reality, blades also …

Accurate predictions of unsteady forcing on turbine blades are essential for the avoidance of
high-cycle-fatigue issues during turbine engine development. Further, if one can …

This dissertation provides numerical studies to improve bladed disk assembly design for
preventing blade high cycle fatigue failures. The analyses are divided into two major …
