Abstract In a turbine of a jet engine, deposition phenomenon is often observed.
Deposition is a phenomenon that particles such as volcanic ash, sand and dust
passing through a combustion chamber of a jet engine are melt, rapidly cooled
and then accumulate on the turbine blade and end-wall surfaces. Deposition is
one of critical problems when aircraft flies in a cloud with many particles.
Obviously, deposition can degrade the aerodynamic performance of the turbine
blade and vane, and make partial or complete blockage of film-cooling holes. As
the result, deposition deteriorates safety and life time of the turbine. In the past… More >
