The Geared Turbofan technology is one of the most promising engine configurations to significantly reduce the specific fuel consumption.
In this architecture, a power epicyclical gearbox is interposed between the fan and the low pressure spool.
Thanks to the gearbox, fan and low pressure spool can turn at different speed, leading to higher engine bypass ratio.
Therefore the gearbox efficiency becomes a key parameter for such technology.
Further improvement of efficiency can be achieved developing a physical understanding of fluid dynamic losses within the transmission system.
These losses are mainly related to viscous effects and they are directly connected to the lubrication method.
In this work, the oil injection losses have been studied by means of CFD simulations.
A numerical study of a single oil jet impinging on a single high speed gear has been carried out using the VOF method.
The aim of this analysis is to evaluate the resistant torque due to the oil jet lubrication, correlating the torque data with the oil-gear interaction phases.
URANS calculations have been performed using an adaptive meshing approach, as a way of significantly reducing the simulation costs.
A global sensitivity analysis of adopted models has been carried out and a numerical setup has been defined.
