Influence of the Thermal Diffusion of the Sand Bed on the Evolutive Process of the Wind Blown Sand Flux
不同地表温度的热扩散对风沙流的影响

A theoretical model with considering the thermal diffusion (TD) from the sand-bed is used to study the effect of the TD during the evolution of the wind-blown sand flux. And in the wind-blown sand flux the coupling interaction is taken into consideration among wind speeds in the vertical and horizontal directions, and the sand movement. The numerical results show that it is quite obvious for the evolutive process of the sand-driving wind affected by the TD of the bed. When the wind-blown sand flux reaches a...
