Loss mechanisms in a highly loaded transonic axial turbine stage
Flow in a one-and-a-half stage highly loaded transonic axial turbine representative of future generation turbine technology is assessed for its role in loss generation. Steady and unsteady two-dimensional and three-dimensional flow computations, complemented by simplistic control volume analyses as …

Aerodynamic performance measurements of a film-cooled turbine stage
… out at the MIT Blowdown Turbine Facility using a highly loaded turbine stage. The Blowdown Turbine Facility is a short duration test facility capable of testing turbine stages under fully scaled conditions for a test duration of 0.5 seconds. The facility was modified to enable the measurement of …

LEVERAGING CONFINEMENT AND SURFACE EFFECTS TO CONTROL POLYMER PHASE BEHAVIOR AND TRANSPORT PHENOMENA IN POLYMER-INFILTRATED NANOPARTICLE FILMS
Highly loaded, polymer-infiltrated nanoparticle films (PINFs) enable the synergistic combination of polymers with the functionality of nanoscale fillers. Extensive studies have found that their behavior deviates markedly from bulk polymers due to extreme confinement and high interfacial area within …
