本文以粘性流体的边界层理论为基础,推导推力轴承热弹流计算中油膜能量方程进油温度边界条件计算式;通过弗克讷-斯肯流动的相似性解建立了瓦块进油侧面与油的热交换系数的计算关系式,并与实验结果进行比较。 Based on the boundary layer theory of viscous fluid, this paper deduces the calculation formula of the oil temperature boundary conditions for the oil film energy equation in the calculation of the thermo-hydro flow of thrust bearings. By the similarity of the Fockne-Skein flow, Oil heat exchange coefficient of the calculation formula, and compared with the experimental results.
