关于落球回弹弹流理论的研究

Research on EHD theory of a ball falling and rebounding

用数值分析方法建立了落球回弹弹流问题的基本方程（包括牛顿体和非牛顿体），并给出了计算方法和程序，所采用的方法具有收敛快、精度高、可移植性强等优点；结合一个算例给出了主要结果．此项研究为流变润滑理论的发展和新型落差式流变仪的研制给出了理论基础．

The basic equations of EHD problem of a ball falling-rebounding (including Newtonian and non-Newtonian fluids) have been derived using numerical analysis. New calculating methods and programs have been developed. The new ways have excellent conergent speed and accrcy, and good ability of transition The calculating results of a typical example have been given. It will become the theory basis for the development of elastohydrodynamic lubrication and research and manufacture of new rheological meter.
