1. Luk, Daniel H. Steady Heat Transfer Predictions For A Highly Loaded Single Stage Turbine With Flat Tip.

Degree: MS, Aeronautical and Astronautical Engineering, 2008, The Ohio State University

This thesis presents steady computational predictions for a single stage (2-blade-row), highly loaded, turbine. Computational predictions and experimental measurements of heat flux are compared for both the stator vane and the rotor blade with a flat tip. Comparisons for both blade rows are presented at three different spanwise locations as well as on the hub and casing endwalls and rotor tip. The experimental measurements were taken from earlier experiments conducted at the Ohio State University Gas Turbine Laboratory Test Facility. The computational predictions were achieved using TURBO. This CFD code is a 3D, Reynolds-Averaged Navier-Stokes (RANS), computational fluid dynamics code capable of handling unsteady flows. The CFD solutions were steady and computed as two separate computations. First, the stator vane simulation was performed using known inlet and exit boundary conditions. Then, inlet boundary conditions for the rotor blade simulation were taken from radial exit profiles of the steady stator vane solution and exit boundary conditions for the rotor blade was taken from previous CFD solutions which involved a 3-blade row simulation. The CFD heat transfer predictions compared well with the stator vane experimental values. The CFD heat flux prediction comparisons with the experimental measurements for the rotor blade were only fair. The largest percent error between the computation and the experimental measurements was 25%. The predictions for the hub of the rotor blade had good agreement with the experimental data. Most of the predictions were within the tight scatter of experimental data. The CFD heat transfer prediction for the rotor tip had good agreement with previous computational predictions but only fair agreement with experimental data. The rotor tip predictions for heat transfer were on average 15.5% greater than the experimental measurements. The rotor blade casing surface heat transfer results are presented in this thesis, however there were no other data for the results to be compared to. Detailed analysis and discussion over the CFD predictions and results are contained in this thesis.
