分析了无偏心旋转环形密封中稳态、湍流的两相流体流动。流体被假定为处于热力学平衡的液体和蒸汽的均匀混合物。此外，流动被假定为绝热的，但由于粘性耗散产生的热量的影响是充分占。模型的控制微分方程的解决方案是通过使用一个四阶龙格-库塔数值积分方案。讨论了阻塞和非阻塞条件下质量泄漏率的计算，解释了全液体阻塞流动现象。以低温氧为密封流体，给出了几个数值算例。1986年5月12日至15日在加拿大安大略多伦多举行的第41届年会上发表
Steady, turbulent two-phase fluid flow in a rotating annular seal with no eccentricity is analyzed. The fluid is assumed to be a homogeneous mixture of liquid and vapor in thermodynamic equilibrium. Further, the flow is assumed to be adiabatic, but the effects due to heat generation by viscous dissipation are accounted for fully. Solution of the model governing differential equations is accomplished by use of a fourth-order Runge-Kutta numerical integration scheme. The calculation of mass leakage rates under choked and unchoked conditions are discussed and the phenomenon of all-liquid choked flow is explained. Several numerical examples are presented supposing cryogenic oxygen as the sealed fluid. Presented at the 41st Annual Meeting in Toronto, Ontario, Canada May 12–15, 1986
