Fouling in gas turbines is caused by airborne contaminants which, under certain conditions,
adhere to aerodynamic surfaces upon impact. The growth of solid deposits causes …

Fouling affects gas turbine operation, and airborne or fuel contaminants, under certain
conditions, become very likely to adhere to surfaces if impact takes place. Particle sticking …

Abstract CaO-MgO-Al 2 O 3-SiO 2 (CMAS) melting and then sticking in the film cooling holes
is one of the important factors causing the cooling performance degradation of gas turbines …

A methodology for informing physics-based impact and deposition models through the use
of novel experimental and analysis techniques is presented. Coefficient of Restitution (CoR) …

In order to have a further insight into the dynamic build-up process of particle deposits within
the high-pressure turbine stator of an aeroengine and also into their effects on aerodynamic …

Characteristics of particle migration and deposition were numerically investigated in
presence of aggressive swirl at the turbine inlet. The isolated effects of the inlet swirl were …

This study numerically investigates film-cooling performance and particle trajectories in
AGTB (two rows of cylindrical holes equipped on suction side (SS) and pressure side (PS) of …

Fine particles of ash and sand can deposit on the surfaces of cooling ducts, diminishing heat
transfer efficiency and threatening the operation of turbine engines. The surface roughness …

The gases discharged from the new generation of lean-burn combustors usually have hot
streaks (HS) and swirls. The thermal performance of rotor thermal barrier coatings (TBCs) …

In this paper, to demonstrate the deposition effects on cooling performance, the changing
patterns of film cooling due to particle deposition are numerically investigated on a turbine …
