Simulation of Supersonic Combustion in Three-Dimensional Configurations

摘要

A turbulence model that calculates the turbulent Prandtl and Schmidt numbers as part of the solution, addressesnturbulence/chemistry interactions, and accounts for compressibility effects is used to simulate supersonic combus-ntion in two three-dimensional experiments: the SCHOLAR experiment, which employs vitiated air and hydrogennfuel, and the HyShot experiment, which employs air and hydrogen fuel. Two chemical kineticmodels are employed:none employs reaction rates that are functions of temperature,whereas the other employs rates that are both functionsnof pressure and temperature. In general, fair to good agreement is indicated with available measurements.
