| 摘 要： | 对定向运动流体,建立流体分子按定向漂移速率分布的规律, 由之得出定向运动流体分子按分子横向运动速率分布所遵循的规律,以定向运动流体分子横向运动分量平均速率作为确定湍流现象发生的参数,从而构成了对用雷诺数可以确定湍流的微观解释.在定向运动流体中,建立流体分子按势能分布的规律.通过在定向运动流体中引入麦克斯韦速率分布律及玻耳兹曼分布律,确立了定向运动流体中分子所遵循的统计规律.

| Abstract: | To the directional motion fluid,the speed distributed rule of fluid molecule were established according to the direction drift,the rule of the directional motion on fluid molecule were obtained according to the molecular transversal motion speed rate distribution.Regard the average speed of the directional motion fluid molecule transversal motion component as the parameter of turbulent flow occurrence,constituted to has used the Reynolds number can determine the microscopic explanation of turbulent flow.In ... |
