An aeroelastic solver is developed using a nonlinear frequency domain flow solver coupled
to a plate-bending finite element linear structural solver. A methodology for determining the …

The aerothermal performance of a high pressure turbine is critically influenced by the tip
leakage flow established in the clearance between the shroudless rotor blade tip and the …

Geometrical variations occur in highly loaded turbine blades due to operation and
regeneration. To determine the influence of such regeneration-induced variances of turbine …

WING flutter is a well-known aeroelastic phenomenon that can cause serious damage or
even destroy an aircraft when a certain limit speed is exceeded [1, 2]. However, in an …

Abstract The Harmonic Balance method for simulating unsteady nonlinear periodic flows is
presented in this paper. Its recent, yet rapid development was motivated by the possibility of …
