Abstract

Abstract

Laser diagnostic techniques are essential for performing time-resolved studies of solid rocket propellant combustion and small explosives detonations. Digital in-line holography (DIH) is a powerful tool for three-dimensional particle tracking in complex multiphase flows. By combining DIH with complementary diagnostics, particle surface temperatures and soot/smoke properties can also be identified.

Abstract

Abstract

Planar laser diagnostics, including particle image velocimetry and laser-induced fluorescence, are commonly used in engine combustion research. This talk discusses some of the challenges and opportunities for using planar diagnostics to understand the complex, turbulent flow/flame coupling present in military engine combustors.

Abstract

Abstract

KHz-rate (aka high-speed) imaging diagnostics for propulsion R&D have advanced rapidly in the past decade along with camera technology and laser systems. This presentation will i) summarize the state of high-speed imaging diagnostics and ii) describe some uses of high-speed diagnostics related to high-speed propulsion.
