Numerical simulation of high-speed combustion chamber by OpenFOAM

The flows of multicomponent media with turbulence and combustion for the numerical study of gas-dynamic processes in the model ramjet/scramjet engine are considered. To provide ignition of mixture the short time channel lock by compressed air is used. The lock is performed across the main flow. The flow regimes of multicomponent mixture without combustion and with combustion of fossil fuels are considered. The verification of calculations with the help of demonstration of the convergence of approximate solutions by mesh refinement is performed. The calculations use a hybrid supercomputer K-100, tools for working with graphics, as well as the MPI library — for the communication between computing nodes.
