Additive manufacturing (AM) has had an enormous impact on the manufacturing sector. Its
role has evolved from printing prototypes to manufacturing functional parts for a variety of …

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 …

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 …

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 …

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 …

We present a numerical study analysing the breakup of a single cohesive particle aggregate
in turbulence. Solid particles with diameters smaller than the Kolmogorov length scale (. A …

Experiments have been performed to assess the effects of particle loading, size, and
temperature on flow blockage development in a geometry representative of a gas turbine …

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 …

Deposition of particles ingested into the hot turbine component of an aircraft engine could
lead to degradation of turbine cooling performance and thus reduces service lifetime. It is …

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 …
