Ablation and ignition by impinging jet flows
(2013-12)Two separate heat transfer problems that involve jet flows impinging on a reacting target are studied through modeling and experimentation. The first system is an ablating carbon-carbon specimen exposed to high heat fluxes ... -
Characterization of ablative properties of thermoplastic polyurethane elastomer nanocomposites
(2010-12)The advancement of each component of aerospace vehicles is necessary as the continual demand for more aggressive missions are created. Improvements in propulsion and guidance system electronics are invaluable; however ... -
An electrostatic approach for producing nanoparticulate membranes using laser ablation of microparticle aerosols
(2011-08)The Laser Ablation of Microparticle Aerosols (LAMA) process produces nanoparticles by ablating microparticles that are entrained in an aerosol. Two of the main advantages of this process are that the particles produced ... -
Investigation and modeling of coupled thermochemical and thermomechanical erosion in thermally degrading systems
(2012-05)The coupled effects of thermochemical and thermomechanical erosion are investigated. A quasi-steady ablation model with finite rate surface chemistry is developed and applied to a solid carbon combustion scenario to ... -
Oxide-metal nanoparticles using laser ablation of microparticle aerosols
(2009-08)We have studied a continuous aerosol process for producing oxide nanoparticles with sizes of 10-60 nm that are decorated with smaller 1-3 nm metallic nanoparticles. Such particles may be useful in a number of areas including ... -
Photoacoustic image guidance and tissue characterization in cardiovascular applications
(2016-12)Collectively, cardiovascular diseases continue to be the leading cause of death, across nations and across decades. Improved diagnostic imaging methods offer promise to alleviate the morbidity associated with these diseases. ... -
Quantitative measurements of ablation-products transport in supersonic turbulent flows using planar laser-induced fluorescence
(2015-08)A recently-developed experimental technique based on the sublimation of naphthalene, which enables imaging of the dispersion of a passive scalar using planar laser-induced fluorescence (PLIF), is applied to a Mach 5 turbulent ... -
RF/microwave absorbing nanoparticles and hyperthermia
(2009-12)The primary purpose of this work was to evaluate the capability of nanoparticles to transform electromagnetic energy at microwave frequencies into therapeutic heating. Targeted nanoparticles, in conjunction with microwave ... -
Technique for imaging ablation-products transported in high-speed boundary layers by using naphthalene planar laser-induced fluorescence
(2010-08)A new technique is developed that uses planar laser-induced fluorescence (PLIF) imaging of sublimated naphthalene to image the transport of ablation products in a hypersonic boundary layer. The primary motivation for this ... -
A toolkit for characterizing uncertainties in hypersonic flow-induced ablation
(2010-12)A one-dimensional, quasi-steady ablation model with finite rate surface chemistry and frozen equilibrium pyrolysis gases is developed and discussed. This material response model is then coupled to a film-transfer boundary ...
