Abstract:

This final technical report consists of two interim progress report received from the grantee in Nov. 2011 and Sept. 2013. Pressure gain combustion has the potential to increase gas turbine efficiency by more than 10. There is gap in the technology necessary for such improvements. Namely, conventional turbines do not work efficiently in the unsteady flow produced by pressure gain combustors. This effort was to examine the problem using simplified experiments and numerical simulations to reveal the fundamental fluid mechanics of these unsteady flows. Specifically investigated were the effects of the geometry, jet Mach number, frequency, and temperature.
