Hodges, Ben R., Auteur ; Teng, Michelle H., Éditeur scientifique |Application of Crank-Nicolson (CN) discretization to the hydrostatic (or shallow-water) free-surface equation in two-dimensional or three-dimensional Reynolds-averaged Navier.Stokes models neglects a second order term. The neglected term is zero[...]

Bernhard Cosic, Auteur ; Thoralf G. Reichel, Auteur ; Christian Oliver Paschereit, Auteur |Helmholtz resonators are often used in the gas turbine industry for the damping of thermoacoustic instabilities. To prevent thermal destruction, these devices are usually cooled by a purging flow. Since the acoustic velocity inside the neck of t[...]

Yuan Liu, Auteur ; Manuj Dhingra, Auteur ; J. V. R. Prasad, Auteur |An active engine control scheme for protection against compressor instabilities such as rotating stall and surge is presented. Compressor stability detection is accomplished via a parameter known as the correlation measure, which quantifies the [...]

Tian-Wei Ma, Auteur ; Yang, Henry T., Auteur ; Ghanem, Roger G., Éditeur scientifique |This paper proposes a combined feedback-feedforward control algorithm for reducing structural response of buildings to seismic excitations. The controller contains both feedback and feedforward components. The feedback component is assumed to be[...]

Stergiopoulos, John, Auteur ; Tzes, Anthony, Auteur |Input shaping is a technique that seeks to reduce residual vibrations of lightly damped systems through modification of the command input to the system. Although several input shaping techniques have been derived primarily from linear system the[...]

Smitha Mani, Auteur ; Parimi, Surya Kiran ; Sahjendra N. Singh, Auteur ; Woosoon Yim, Auteur |This brief paper treats the question of adaptive control of a projectile fin using a piezoelectric actuator. The hollow projectile fin is rigid, within which a flexible cantilever beam with a piezoelectric active layer is mounted. The model of t[...]
