利用互补性的概念，发展了一种新的雷诺方程的质量守恒公式。这种新的方法克服了以前与使用这种互补制剂解决空化问题有关的缺点，其中发生液膜的再形成。验证对一些分析和半分析配方，包括纹理轴承和挤压油膜阻尼器的各种问题，进行。目前的配方是在非常好的协议与现有的分析和数值质量守恒的解决方案。
A new mass-conserving formulation of the Reynolds equation is developed using the concept of complementarity. This new method overcomes the drawbacks previously associated with the use of such complementarity formulations for the solution of cavitation problems in which reformation of the liquid film occurs. Validation against a number of analytical and semi-analytical formulations, for a variety of problems including textured bearings and squeeze film dampers, is performed. The current formulation is shown to be in very good agreement with existing analytical and numerical mass-conserving solutions.
