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
- 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.
