ALE-based finite element modeling of needle-punching using embedded 1D yarns in a 3D preform

Needle-punching is widely used to introduce through-thickness reinforcement into fibrous preforms for composite materials. During the process, barbed needles repeatedly penetrate stacked layers and transfer fibers from the in-plane directions toward the thickness direction, progr...

Analysis of Injector Staging Patterns With Comparisons of Limit Cycle Amplitudes Over a Full Domain of Operation

Abstract Injector staging has recently been demonstrated to control thermoacoustic instabilities in an annular combustor, but its effects were investigated at a single operating point. This work extends this concept to a wide operating domain comprising a range of thermal powers...
