(2021-08-02)There are significant challenges involved in the design of hypersonic vehicles/projectiles, one of them being the fluid dynamics on the surface. The fluid dynamics can affect the thermal load, structural load and handling ...
-
(2013-05-15)A key remaining challenge in the design of hypersonic vehicles is the incomplete understanding of the process of boundary-layer transition. Turbulent heating rates are substantially higher than those for a laminar boundary ...
-
(2023-04-19)High-fidelity computational fluid dynamics simulations are imperative to understanding the complex physics of hypersonic flight. Of the many complex flow fields in hypersonic flows, Mach stems are a particular area of ...
-
(2021-07-22)The BOundary Layer Turbulence (BOLT-II) flight experiment proposed by the Air Force Office of Scientific Research (AFOSR) is a joint collaboration between academia, industry, and government partners to advance the understanding ...
-
(2022-12-09)Efficient high-speed air breathing propulsion is a key enabling technology for robust long distance hypersonic flight. However, the physics that drive the design of these propulsion systems was extremely complex with a ...
-
(2023-04-21)Boundary-layer transition from laminar to turbulent flow critically affects vehicle safety and performance, particularly at hypersonic speeds where heat-transfer rates are extreme. Accounting for transition effects requires ...
-
(2011-08-08)Aerospace structures with large aspect ratio, such as airplane wings, rotorcraft blades, wind turbine blades, and jet engine fan and compressor blades, are particularly susceptible to aeroelastic phenomena. Finite element ...
-
(2012-10-19)Infrared transition location estimates can be fast and useful measurements in wind tunnel and flight tests. Because turbulent boundary layers have a much higher rate of convective heat transfer than laminar boundary layers, ...
-
(2009-05-15)Computational investigations were carried out on an advanced serpentine jet engine inlet duct to understand the development and propagation of secondary flow structures. Computational analysis which went in tandem with ...
