Freezing of the flight environment of an aircraft occasionally causes the congealing of oil in the oil coolers. Although decongealing tests and re-designs require longer durations, many studies have examined the cooling loss arising from this phenome

Open-cell metal foams are often used in applications where particulate and/or droplet capture is important. Here a Computational Fluid Dynamics (CFD) modelling approach is described which models the metal foam at both the pore-scale and the macroscop

In the present study, an improved heat exchanger model is proposed to efficiently analyze the cold oil removal process inside a fuel-cooled oil cooler. When exposed to low temperature condition, oil within a heat exchanger begins to congeal, preventi

The fuel-cooled oil cooler (FCOC) in the lubrication circuit plays a critical role in the aero gas-turbine engine's aerothermal management. However, the low temperature of the operating environment can congeal the oil and reduce the FCOC efficiency.

In aero-engine bearing chambers, the modelling of shear-driven oil films with the Volume of Fluid method poses significant challenges linked with the need to accurately capture the gas-liquid interaction at the free surface. Typically, the modelling

This paper deals with the wall film dynamics of lubrication oil in the vicinity of the scavenge port of a typical aero engine bearing chamber. Based on the major driving forces influencing the film dynamics, shear forces and gravity, two film flow re

Within the European research project ATOS (Advanced Transmission and Oil System Concepts) a systematic study of the separation efficiency of a typical aero-engine air/oil separator design was conducted. The main objectives were to obtain a basic unde

Hydraulic seals are successfully used to seal gas turbine shaft and bearing chambers because of their main advantages: reliable operation with zero leakage. However, due to the temperature limitations of the lubrication oil their application has been
