Flow field calculation and dynamic characteristic analysis of spherical hybrid gas bearings based on passive grid

Jia, Chenhui; Cui, Zhiwu; Guo, Shijun; Qiu, Ming; Ma, Wensuo (Springer, 2019-01-03)

In order to research the spherical spiral groove hybrid gas bearings, the Realizable k − ε turbulence model of gas film was established based on FLUENT. The simulation calculation method of 6-degrees of freedom passive ...
Research on dynamic characteristics of gas film of spherical hybrid gas bearings based on computational fluid dynamics

Jia, Chenhui; Cui, Zhiwu; Guo, Shijun; Ma, Wensuo (Canadian Society for Mechanical Engineering, 2019-05-16)

A realizable k–ε turbulence model for spherical spiral groove hybrid gas bearing films was established based on computational fluid dynamics (CFD). A six degrees of freedom passive grid was used to calculate the gas film ...
Study on dynamic characteristics of gas films of spherical spiral groove hybrid gas bearings

Jia, Chenhui; Zhang, Haijiang; Guo, Shijun; Qiu, Ming; Ma, Wensuo; Zhang, Zhuangya (SAGE, 2019-01-15)

According to the gas film force variation law, when the bearing axis is slightly displaced from the static equilibrium position, displacement and velocity disturbance relation expressions for the gas film force increment ...
