摘要
给出了定常充分发展流场中风、雪粒相互耦合的运动方程 ,并用简化的雪粒 床面碰撞过程求解了方程 .计算结果表明 ,跃移雪粒对贴地风速有重要影响 ,Magnus效应对贴地风速。
Coupled equations of motion of wind and snow particles for steady state saltation are presented and solved for a simplified grain surface impact process.The results show that saltating snow particles have important effects on wind velocities near surface and Magnus lifting force also has effects on the wind profiles as well as saltating trajectories of snow particles.
