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 …

Fouling afflicts gas turbine operation from first time application. Filtration systems and
washing operations work against air contaminants in order to limit the particles entering the …

Deposition studies were conducted using two impingement jet facilities: a 60 m/s cold jet
(830–950 K) impinging on a heated Hastelloy-X surface (1033–1255 K) and a 215 m/s hot …

The presence and accretion of airborne particulates, including ash, sand, dust, and other
compounds, in gas turbine engines can adversely affect performance and life of …

This study includes the design, validation, and fabrication via direct metal laser sintering
(DMLS) of a gas turbine nozzle guide vanes (NGV) that incorporates three innovative …

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) …

This review article examines the last decade of studies investigating solid, molten, and liquid
particle interactions with one another and with walls in heterogeneous multiphase flows …

The formation mechanism of non-uniform carbon deposition on the turbine blade under the
gas-solid two-phase flow is analyzed, and the finite element model of turbine blade …

Particle deposition in gas turbine engines damages blade surfaces and diminishes engine
performance. Deposition results from heat and momentum exchanges between fluid and …
