在连续介质和滑流区有限长度槽道内的稳定气流,通过整体质量守恒规律得到了沿槽道轴向的压力分布和质量流率的分析表达式。在过渡领域区,也提供了槽道流动压力分布的严格的动理学理论解。在Poiseuille流动的质量流率动理学理论解给定的情况下,压力分布的控制方程被证实是被前一作者从轴承润滑问题移植到解微槽道问题的退化Reynolds方程。同时得到了质量流率分析表达式,它们和现有试验数据的比较相符很好。 The stable gas flow in the finite length channel of continuous medium and slipstream region is obtained by analyzing the pressure distribution and mass flow rate in the axial direction of the channel by the law of conservation of mass. In the transitional area, a rigorous kinetic theoretical solution to the flow pressure distribution in the channel is also provided. Under the Poiseuille flow theory of mass flow rate kinetics, the governing equations of pressure distribution proved to be degenerated Reynolds equations that were transplanted from bearing lubrication problems to denesting channels by a previous author. At the same time, mass flow rate analysis expressions were obtained, which are in good agreement with the existing experimental data.
