频繁的碰撞作用和很大的流速梯度是增强颗粒脉动的两大主要原因，其对轻颗粒的影响大于对重颗粒的影响。 | | 2. | 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
通过对细小颗粒在剪切流场中运动方程的fourier分析，得到了颗粒脉动强度和流体脉动强度之间的定量关系，表明颗粒粒径、颗粒密度、流速梯度以及紊动场含能旋涡的特征频率是影响颗粒脉动强度的主要因素，首次从理论上证明了在一定条件下，颗粒在纵、垂向的脉动强度均会超过相应的流体脉动强度，为已有的实测资料提供了合理的解释。 | | 3. | And , we also have had the relation between the size of the horizontal circulation regions and the fr number around the dike for the flow - deflection method . the results of this study show that , using the method of flow - deflection or " sucking - spouting " water , the flow pattern can be improved , the size of the horizontal circulation regions and the sedimentation volume caused by the horizontal circulation can both be reduced . so , they can be adopted to improve the navigation condition of upper approaching channel of three gorges project , which could guarantee the safety of navigation
通过试验，得到了以下创新的成果： 1 、不加吸、喷水时，丁坝后的回流长度约为丁坝长度的8倍； 2 、加吸、喷水可以减小丁坝后的回流尺度和强度，并得出了有理论根据的吸、喷流量与回流尺度减小之间的定量关系以及吸、喷流量与丁坝周围流速梯度之间的定量关系； 3 、加吸、喷水可以减小回流淤积，并得出了吸、喷流量与淤积量减小之间的定量关系以及回流尺度减小与淤积量减小之间的定量关系； 4 、加导流板可以减小丁坝后的回流尺度，并得出了丁坝周围的水流fr数与回流尺度减小之间的定量关系。 |
