本文对液压流体力学中雷诺方程边界条件──固液界面无滑移的经典假设的普适性提出质疑,应用物理化学的理论论述了是否出现界面滑移的基本判据,并进行了对比试验,首次证实了在一定条件下界面上会出现滑移现象,突破了沿袭数百年的界面无滑移的经典假设。这一新发现不仅有重大的学术意义,而且对改进和提高液压元件和其他机械基础件性能将产生深远影响。
This paper questions the universality of classical assumptions of the Reynolds equation in hydraulic fluid mechanics - the slip-free solid-liquid interface, and discusses the basic criteria for the occurrence of interface slip based on the theory of physical chemistry. , For the first time confirmed that there will be slippage on the interface under certain conditions and broke through the classic assumptions of no-slip interface for hundreds of years. This new discovery is not only of great academic significance, but also has a profound impact on improving and enhancing the performance of hydraulic components and other mechanical foundations.
