Abstract |
|
Journal bearings are used to support the rotors in high speed applications such as turbines, i.c. engines etc. Most of the design formulae used in the design of journal bearings are based on isothermal hydrodynamic model which is not realistic. In this work, different input parameters effect on thermo hydrodynamic lubrication model (i.e. Effect of temperature on the viscosity is include in the computation) is performed to arrive at the various performance parameters such as pressure developed, load carrying capacity etc. by availing Ansys Fluent. Computational fluid dynamics is a branch of numerical methods which finds increasing use nowadays in the lubrication industry. Finite volume method is the basic framework of fluent software. |
