Flow Characteristics in an Inter-Turbine Duct Under Off Design Conditions
Bibliographic record
Abstract
In the present numerical study, flow characteristics of an aggressive inter-turbine duct under design and off-design inflow conditions, are reported. Two duct geometries (1) un-strutted and (2) strutted are considered. An un-strutted duct with sector angle of 20 o and a strutted duct with 40 o sector angle are analyzed. The performance of the duct is evaluated using static pressure recovery and total pressure loss. For simulating off design conditions, the duct inlet boundary is imposed with a typical tip leakage profile (reminiscent of the exit flow from the preceding high pressure turbine stage) and swirl. The swirl is varied between 10 o to 30 o . Under off-design conditions, the un-strutted duct shows only marginal deviation in its performance. However, the strutted duct showed a significant increase in loss under off-design conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
