内容記述 | In this paper, the applicability of simulation model of powder snow avalanches is examined by the experimental results of inclined thermals with suspended solid particles. The simulation model consists of the mass conservation equations for the air and snow particles and the momentum equation, and is called the three-equation model. In the simulation model, the entrainment coefficient is expressed by a linear function of the slope angle of the bottom. This model is examined by the experimental data of inclined thermals using the mixture of water and solid particles. The reasonable numerical results are obtained in terms of the longitudinal variations of the height, the speed, the volume of solid particles in the thermal. | |||||
