Title: A Multi-scale Computational Framework for Property Prediction of Fluids
Presenting author: Marianna Yiannourakou
Symposia: D8. Multiscale and Multiphysics Modelling of Materials, Processes and Devices
Presentation type: Oral presentation
Here is the abstract:
A multi-scale computational model has been developed for application to the micro- and macro-scale thermo-fluid-dynamics in high speed gear systems. At the micro-space/time-scale, a model of gear mesh lubrication film transport and heating is presented based on elastohydrodynamic lubrication (EHL) tribology and mesh kinematics. At the macro-space/time-scale, computational fluid dynamics (CFD) tools are used to resolve the time-dependent conduction and convection (windage) processes within the gears and gearbox. Scale-spanning averaging procedures were developed for coupling the instantaneous meshing and macro scale physics. The overall method is presented and applied to an equilibrium mist-lubricated gearbox configuration tested at the NASA Glenn Research Center. © 2013 by the American Helicopter Society International, Inc.
