Numerical Analysis on Gas-solid Two Phase Flow Field around 2-D Jet Vane

摘要

The flow around the 2-D jet vane is characterized by a two-phase flow including Al2O3 particles generated by combustion chamber. Basing compressible time-averaged Navier-Stokes equation , by the method of RNG k- ? turbulence model under high Reynolds number and Euler-Lagrange two phase model,gas-solid two-phase flow field around 2-D jet vane is studied. The particle trajectory and Mach contour around 2-D jet vane are achieved by numerical simulation. The curves of pressure and temperature on 2-D jet vane are given. The influence of particle size on flow field is analyzed. The particle size are considered as the parameters are 1 ? m,5 ? m ,10 ? m and 16 ? m,respectively. The calculated results present the flow status and properties of the flow around the 2-D jet vane. The results are helpful to the aerodynamic design of jet vane.
