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 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 …

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) …

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 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 …

Ash particle deposition in a high-pressure turbine stage was numerically investigated using
steady Reynolds-averaged Navier-Stokes (RANS) and unsteady Reynolds-averaged Navie …

A hot sand model has been developed to predict the rebounding and sticking behavior of
environmental particulates in the hot section of a gas turbine. This paper will focus on the …

The aircraft engine hot section is most vulnerable and failure prone to environmental particle
ingestion, which, particularly for helicopters, can cause detrimental effects ranging from …

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 …

This paper presents a review of particle deposition research in film-cooled gas turbines
based on the recent open literature. Factors affecting deposition capture efficiency and film …
