Numerical Simulation of Cryogenic Injection in Rocket Engine Combustion Chambers

The numerical simulation of cryogenic combustion is crucial for a better understanding of the complex physics involved in reactive flows of rocket engines and to help to reduce the development cost of these engines. The focus of this study is set on the oxidizer injection and its dispersion through jet dense core destabilization and atomization or supercritical mixing. Specific models have been...

Monte Carlo Simulation of Particle Radiation in High Altitude Solid Rocket Plumes (Invited)

Several recently developed numerical schemes are used in an integrated framework to simulate the plume flow from a representative solid propellant rocket at an altitude of 114 km. In nonequilibrium regions the gas is modeled using the direct simulation Monte Carlo method, while a particle simulation method based on a simplified approximation of the Boltmann equation is used in near-equilibrium ...

Numerical Simulation of Weakly Ionized Hypersonic Flow for Reentry Configurations

Numerical simulations of axisymmetric flows over reentry configurations at hypersonic conditions using a Navier-Stokes solver are presented. The Navier-Stokes equations are modified using Park’s two-temperature model to account for thermochemical nonequilibrium and weak ionization effects. The finite-volume method is used to solve the set of differential equations. The code has the capability t...
