Abstract This paper presents the results of investigations into the applicability of the Reynolds equation for analyzing near field levitation (NFL) phenomena. Two separate approaches were developed, experimentally verified, and applied to meet the research objective. One was based on the Reynolds equation and the other was based on general conservation equations for fluid flow solved using computational fluid dynamic (CFD). Comparing the calculation results revealed that, for certain operating conditions, differences in the predicted system parameters appear. It was proven that both the Reynolds and Helmholtz numbers define border operating conditions for the applicability of the Reynolds equation to analyze NFL problems.

关于雷诺方程在分析高速近场悬浮现象中的适用性的思考

摘要 本文介绍了雷诺方程在分析近场悬浮 (NFL) 现象方面的适用性的研究结果。开发、实验验证并应用两种不同的方法来满足研究目标。一种基于雷诺方程，另一种基于使用计算流体动力学 (CFD) 求解的流体流动的一般守恒方程。比较计算结果表明，对于某些操作条件，预测的系统参数会出现差异。事实证明，雷诺数和亥姆霍兹数都定义了雷诺方程用于分析 NFL 问题的适用性的边界操作条件。
