Modeling of detonation of a C2H4/O2/N2 mixture in rectangular and circular channels on a hybrid computational cluster

Modeling of detonation of a C2H4/O2/N2 mixture in rectangular and circular channels on a hybrid computational cluster

Numerical simulations of a detonation wave propagation in plane, rectangular and circular channels are performed and the formation of cellular structure is studied. A comparison of a detonation wave instability development in various channels is made. All numerical simulations are performed with an...

description Numerical simulations of a detonation wave propagation in plane, rectangular and circular channels are performed and the formation of cellular structure is studied. A comparison of a detonation wave instability development in various channels is made. All numerical simulations are performed with an in-house numerical code on hybrid supercomputers. The code is written in C++ with the use of MPI, OpenMP and CUDA parallel technologies. AFRL chemical reaction mechanism for description of ethylene/oxygen/nitrogen mixture combustion is considered.
