Oil Droplet Impact Dynamics in Aero-Engine Bearing Chambers - Correlations derived from Direct Numerical Simulations
Abstract:
The understanding of the two-phase flow in bearing chambers is crucial for an efficient and reliable operation of future aero-engines. This scientific report investigates the oil droplet impact dynamics for typical impingement regimes relevant to bearing chambers. The application of a Direct Numerical Simulation based on the Volume-of-Fluid method and coupled with an adaptive mesh refinement technique allowed to gain new insights into these dynamics to date not reported in scientific literature.
