| Abstract: | finite-volume method is used for prediction of two-phase incompressible turbulent flow in combustors of solid rocket motors. Multi-region grid method is adopted for complex irregular geometries. Body-fitted grid is generated for the calculation. In a nonstaggered grid system,momentum interpolation method is utilized to calculate the velocities at cell face in order to eliminate unphysical pressure oscillations. Turbulence is simulated by two-equation closure model along with the wall function method f or the near wall region. Particle trajectory model is used to describe the motion of the particles in the two-phase flow. Numerical calculation of the gas-particle two-phase flow is Performed by PSIC method given by Crowe et al.. Two cases for the flow field in chamber with conical type grain are calculated by above-mentioned methed. |
