Application of the Continuous Rotating Detonation to Gas Turbine

TLDR

The study presents experimental research on rotating detonation conducted at the Institute of Aviation in Warsaw. The authors performed 3‑D numerical simulations of detonation propagation in cylindrical chambers with kerosene‑hydrogen‑air mixtures, analyzed flow–detonation interactions and outflow thermodynamics, and selected chambers for GTD‑350 engine tests based on these results. Extensive testing of continuously propagating rotating detonation in various chambers and fuel‑air mixtures demonstrated that its application to the GTD‑350 engine can increase engine efficiency.

Abstract

In this paper experimental research on rotating detonation carried out at the Institute of Aviation (IA) in Warsaw are presented. Research was focused on 3-D numerical simulations of detonation propagation in cylindrical chambers and on evaluation of conditions at which rotating detonation is propagating in cylindrical channels for kerosene-hydrogen-air mixtures. Conducted simulations are used for analysis of complex flow – detonation front interaction and for estimating the thermodynamic parameters of the outflow gases. Extensive research on continuously propagating rotating detonation in many different chambers and in different fuel-air mixtures were tested. On bases of conducted calculations, as well as results of experimental study, a few chamber were selected for tests with GTD-350 engine. It was shown that application of the continuously rotating detonation to GTD-350 engine can results with increased efficiency of the engine.
