根据模拟的风沙跃移层中风速廓线分布结果,讨论了电场力对风沙流中气载剪切力和颗粒作用于单位体积气流的体积力的影响.结果表明:沙粒带正电荷时的气载剪切力和颗粒作用于单位体积气流的体积力最大,不带电荷时次之,沙粒带负电荷时的气载剪切力和体积力最小.
Based on the numerical results of wind velocity in wind-blown sand saltation, the effects of electrostatical force on the air-borne stress and the force per unit volume exerted on the wind by the blown sand cloud were studied. The results showed that the air-borne stress and the force per unit volume exerted on the wind reached the maximum for q 〉 0, and reached the minimum for q 〈 0.
