Combustion with Total Pressure Increase.
Abstract
Combustion with pressure increase is shown to be a means of achieving a very substantial increase in the efficiency of the gas turbine cycle. In this research a first order travelling tangential wave is utilized. The first order to the travelling tangential wave is known, to be capable of particularly high non-dimensional pressure amplitudes, as well as capable of producing continuous pressure increases (instead of pulsations). A simple model cavity is used to study the oscillation, and leads to an unambiguous method of identification of the first order travelling tangential wave. Novel means of exciting the wave are attempted. The method of angled jets is shown to be capable of driving the oscillation to high (50% peak to peak) non-dimensional pressure amplitude. The Vernier Valve, a new invention, also gives rise to the oscillation. (Author)
