| 内容記述 | Sand movement by wind is studied in detail in this paper. The effect of wind turbulence on sand particles is neglected by taking into accounts their susceptibility in the natural wind. Sand particles move downstream with bouncing motions near the sand surface and in the stationary state they gain on an average as much momenta from the wind as they lose at the moment of collision on the sand surface. From this, the relation between the rate of sand flow quantity and the friction velocity of the wind is derived, which agrees very well with the experimental results in the wind tunnel and field. The statistical treatments of the phenomena make it possible for us to calculate the vertical distributions of density of sand particles and quantity of sand flow, which again coincide completely with experiments. It becomes clear in this study that the mass of moving sand increases more rapidly in the lower layer than is given in the ordinary diffusion theory. (Received July 19, 1951) | |||||||||
