Analysis of the unsteady overtip casing heat transfer in a high speed turbine
S Lavagnoli, G Paniagua… - Journal of …, 2013 - asmedigitalcollection.asme.org
In modern gas turbine engines, the rotor casing is vulnerable to thermal failures due to large
unsteady heat fluxes. The rotor tip flow unsteadiness is induced by the periodic passage of
the rotor blades, with an intensity dependent on the tip gap geometry. Hence, the
understanding of the physics is of paramount importance to develop appropriate predictive
tools and improve the cooling schemes. The present research aims at providing essential
information on the flow conditions, which should serve to assess the relative impact of the …
