Recently, concerns on environmental problem of the earth are rapidly growing on. One of the typical issues is desertification. To stop or suppress the harmful effects of desertification, the prediction method which can clarify the mechanism of desertification is required. For the purpose it is expected that numerical simulations are very useful. A number of research papers on sand transfer have been published in the literatures. However, they assumed that the sand particle trajectory is parabolic. This assumption would over-simplify the physics. Our final goals are to construct the multi-physics simulation technique which can correctly reproduce sand transfer, and, by applying it, to develop an effective prevention method for desertification. The purpose in the present study is to investigate the effect of particle trajectory computation. Simulating three-dimensional sand transfer around a cube, and comparing the numerical results with the experiments, we confirmed that our method can reasonably predict sand transfer around a cube, and the pressure gradient force should be taken into account in the particle trajectory computation.
