Abstract: The three dimensional complex cold flow field of a gas generator used for a missile control system was numerically simulated using RNG k ε model by the compressible form of the SIMPLE algorithm based on unstructured meshes The numerical results were in agreement with experimental data It is useful in understanding the flow field characteristics in the gas generator, especially in the labyrinthic multilayer lantern rings in it
