Effects of Hot Streak & Phantom Cooling on Heat Transfer in a Cooled Turbine Stage Including Particulate Deposition


Performer: Ohio State University Research Foundation

Project No: FE0007156


Accomplishments


  • Incorporated elastoviscoplasticity (EVP) model which incorporates both elastic and plastic particle deformation. Previous models accounted for either elastic (critical velocity model) or plastic (critical viscosity model) deformation only.
  • Conducted preliminary hot streak clocking study to determine dependency of deposition on hot streak location, particle size, and hot streak severity.
  • Generated hot streaks in TuRFR.
  • Conducted hot streak deposition test with uncooled nozzle guide vanes.
  • Conducted flow simulation of TuRFR test conditions to produce first-ever corroborating computational and experimental data with hot streaks and deposition.
  • Designed and constructed a new high temperature particle impingement test facility for the study of rebound/deposit mechanics of micron-sized particles.
  • Fundamental rebound studies show trends in coefficient of restitution and deposition rate with temperature and velocity. Results will enhance modeling capabilities.
  • Designed and fabricated film slot into existing vane set.
  • Conducted tests with deposition and slot cooling with uniform freestream temperature as baseline.
  • Developed flow model in Fluent for cooled vane.
