高超声速飞行器边界层容易经历层流/湍流转捩, 层流流动和湍流流动在摩擦阻力, 热交换,
噪声和掺混等方面有巨大差别, 转捩问题已成为制约高超声速技术突破的基础科学问题之一 …

For more than half a century, researchers have been aware that freestream fluctuations have
an important effect on laminar-turbulent transition. A century of effort has also been devoted …

This paper documents the programmatic context and considerations that have shaped the
development and execution of a number of research initiatives implemented by the Air Force …

The kinetic modeling of the pyrolysis and combustion of liquid transportation fuels is a very
complex task for two different reasons: the challenging characterization of the complex …

Hummingbirds are the only birds that can sustain hovering. This unique flight behaviour
comes, however, at high energetic cost. Based on helicopter and aeroplane design theory …

The crossflow instability in a hypersonic, laminar boundary layer is investigated using point
measurements inside the boundary layer for the first time. Experiments are performed on a …

The Hypersonic International Flight Research Experimentation (HIFiRE) program is a
hypersonic flight test program executed by the Air Force Research Laboratory and …

This contribution summarizes the current state of research regarding so‐called sensor‐
integrating machine elements as an enabler of digitalization in mechanical engineering and …

A Boltzmann rovibrational collisional coarse-grained model is proposed to reduce a detailed
kinetic mechanism database developed at NASA Ames Research Center for internal energy …

The present thesis constitutes a step forward in advancing the frontiers of knowledge of fluid
