Abstract
The multi-block patching and grid merging technique are adopted to generate computation grid for the complex structure of a jet device control channel. A Runge Kutta method with 5 stage explicit scheme and a multi-grid method are applied to solve the flow model, which includes the whole N S equation, RNG k-ε turbulence model and two layer zonal wall model. On the basis of numerical simulation and fluid field analysis, an improved scheme to the structure of control channel is put forward.
