Numerical simulation of detonation propagation in a plane channel with detailed chemical mechanisms on supercomputers with GPUs

摘要

In this work we present the preliminary results of numerical simulations of detonation wave propagation in a plane channel conducted with an in-home code solving the chemically reacting Euler equations on supercomputers with GPUs. The simulations are performed with four detailed chemical kinetics mechanisms (ONERA, Deiterding, modified Jachimowski, Peterson and Hanson models). The latter model includes a pressure-dependent reaction. The 1D and 2D Euler equations are solved for a hy-drogen/oxygen mixture using high-order shock-capturing TVD schemes and a finite-rate chemistry solver. The sizes of detonation cells obtained with different models are compared.
