In this paper, recent advances in the discrete-element method (DEM) for describing motion,
deposition, agglomeration or aggregation of a large number of adhesive spherical particles …

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 …

Particle deposition on turbine blades poses a significant challenge to the safe operation of
gas turbines. The blockage of film-cooling holes and alteration in the aerodynamic shape of …

Four series of tests were performed in an accelerated deposition test facility to study the
independent effects of particle size, gas temperature, and metal temperature on ash …

This study proposes an improved physical model to predict sand deposition at high
temperature in gas turbine components. This model differs from its predecessor (Sreedharan …

In this paper, effects of four different hole configurations on film cooling performance and
particle deposition are investigated numerically on a curved surface. The RNG k-ε …

Designing film cooling for the leading-edge area of a turbine vane is much challenging due
to the highest thermal load, flow stagnation, as well as distorted incoming flows …

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 …

An improved physical model to predict flyash deposition is developed and discussed in this
paper. This model differs from its predecessor [1, 2] by accounting for deposition of syngas …

Coal ash deposition was numerically modeled on a GE-E3 high pressure turbine vane
passage. A model was developed, in conjunction with fluent™ software, to track individual …
