Numerical simulation of detonation processes in a variable cross-section chamber
Numerical simulation of detonation processes in a variable cross-section chamber
The detonation processes occurring in a combustion chamber with variable cross-sections are numerically simulated for a hydrogen—air reacting flow. The chamber consists of a large diameter tube and two small identical tubes connected on each side through frustums. The channel is closed at the left end and opened at the right. A two-dimensional, time accurate, finite-volume-based method is used to perform the computations. A five-species, two-step global reaction mechanism is used. Two detonation cases are simulated, corresponding to initiation from the closed, left end and the opened, right end. The study showed that area change gave rise to complex wave phenomena. The area change and wave reflections yielded extreme parameters.
