(2021-04-13)Solving nonlinear optimal control problems can be a difficult and time intensive process. This is especially true when the state dynamics of the problem are computationally expensive to solve. Using the Theory of Functional ...
-
(2023-05-01)Reduced-order computational design tools used to model hypersonic shock wave / boundary layer interactions have been known to provide unreliable estimates of surface heat flux and total pressure, which are key parameters ...
-
(2009-05-15)There has been a continuous effort to unveil the physics of hypersonic flows both experimentally and numerically, in order to achieve an efficient hypersonic vehicle design. With the advent of the high speed computers, a ...
-
(2019-04-11)Crossflow instabilities on a 2:1 elliptic cone in hypersonic flow have been investigated in the M6QT and ACE wind tunnels at the Texas A&M National Aerothermochemistry and Hypersonics Laboratory. Experiments on a PEEK 38.1% ...
-
(2023-08-09)For the design of hypersonic vehicles the behavior of the boundary layer and accordingly transition is both critical to understand and simultaneously not very well understood. The stability and transition of high-speed ...
-
(2013-04-22)Prior research in the field of boundary layer turbulence has identified streamwise-elongated large-scale turbulence structures in both low speed compressible and high speed (M=2.0) flow. No experimental work has been done ...
-
(2023-04-20)Adaptive control is a field of control theory dedicated to addressing uncertain and time-varying system models. Multiple-timescale control is dedicated to addressing systems with some states evolving quickly and others ...
-
(2022-12-15)The physics of hypersonic flight is challenging due to the high-temperature environment and presence of chemical and vibrational nonequilibrium. Hypersonic flow over a blunt wedge body is studied for different chemical ...
-
(2022-07-06)Improved modeling of hypersonic turbulent shear layers is of national interest. The Reynolds numbers experienced preclude widespread use of high fidelity simulations, and the complexity of the flow is not captured by simpler ...
