  1. By performing fourier transformation, the relationship between the turbulent intensity of the particle and that of the carrier fluid was obtained which makes clear that particle size, specific gravity, velocity gradient, and the characteristic frequency of energy - containing eddies are four basic influencing parameters. it is proven theoretically that under certain conditions, the stream - wise and transverse particle turbulent intensities exceed those of the carrier fluid. based on the equations of two - phase flow, the presence of fine sediment suspension is shown to attenuate the turbulent intensity of the water

    通過對細小顆粒在剪切場中運方程的fourier分析,得到了顆粒之間的定量關系,表明顆粒粒徑、顆粒速梯以及場含能旋渦的特徵頻率是影響顆粒的主要因素,首次從理論上證明了在一定條件下,顆粒在縱、垂向的均會超過相應的,為已有的實測資料提供了合理的解釋。
