Rotational and Vibrational Raman Spectroscopy for Thermochemistry Measurements in Supersonic Flames (2013-05-31)High speed chemically reacting flows are important in a variety of aerospace applications, namely ramjets, scramjets, afterburners, and rocket exhausts. To study flame extinction under similar high Mach number conditions, ...
-
(Texas A&M University, 2004-09-30)Three different topics of turbulence research that cover modeling, theory and model computation categories are selected and studied in depth. In the first topic, "velocity gradient dynamics in turbulence" (modeling), the ...
-
(2018-10-25)The interaction of turbulence with shock waves, while very common in nature and engineered systems, is a very difficult problem from a theoretical, numerical and experimental perspective. A main challenge comes from the ...

(2022-03-28)The Air Force Research Laboratory/Air Force Office of Scientific Research (AFRL/AFOSR) introduced the Boundary Layer Turbulence (BOLT II) flight experiment to advance the understanding and modeling of naturally occurring ...
-
(2016-05-18)Chaos and turbulence are two important topics in nonlinear dynamics. In this study, two problems related to chaos and turbulence modelling are presented. They are the chaotic vibration phenomenon in high-dimensional partial ...
-
(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 ...
-
(2020-07-08)An emerging trend in the nuclear community is to utilize RANS based turbulence models to supplement thermal-hydraulic system codes in the design of Generation-IV (Gen-IV) power reactors. Prior to full integration into the ...
-
(2016-04-13)Turbulence in high-speed flows is an important problem in aerospace applications, yet extremely difficult from a theoretical, computational and experimental perspective. A main reason for the lack of complete understanding ...
-
(2015-08-07)An ongoing project for the construction of a high-pressure, high-temperature turbulent flame speed vessel is furthered in this study. Prior to this work, a laminar flame bomb apparatus was repurposed as a turbulent flame ...
-
(2012-11-15)Compressibility profoundly affects many aspects of turbulence in high-speed flows - most notably stability characteristics, anisotropy, kinetic-potential energy interchange and spectral cascade rate. Many of the features ...
-
(Texas A&M University, 2006-04-12)Particle Image Velocimetry (PIV) and pressure measurement techniques were performed to investigate the drag reduction due to microbubble injection in the boundary layer of a fully developed turbulent channel flow. ...
