摘要
Turbulent Characteristic Frequency and Spectrum method was studied, the flow turbulent velocity was represented by its Frequency-Spectrum and Fourier modes. Heavy particle dispersion in turbulence flow was simulated Numerically, and the numerical results of large and small sizes particles show good agreement with the experiment results. The method was also used to simulate two-phase flows in engineering problems.
