Numerical Simulation of Rotating Detonation in Cylindrical Channel

In the paper results of two-dimensional numerical simulation of detonation propagation in cylindrical cannel are presented. Calculations were carried out for oxy-acetylene mixtures of a different composition, different location of ignition source, different channel dimensions and different initial velocity of the mixture in the channel. This work is connected with possibility of application of the continuously rotating detonation to jet engine, or so called Rotating Detonation Engine (RDE) descriptions of which could be find in [1]. For calculations a modified program developed by Michel Lefebvr and Toshi Fujiwara from Nagoya University and modified at Warsaw University of Technology was used [2]. Two different combustion models were used. The first simplified model based on data available in [3],[4] an model developed by Williams and described in the paper „The Combustion and Oxidation of Acetylene” [5]. Both models were verified on base of available literature data described in [6]. Most of the calculations were based on the second approach. The following reactions were taken into account:
