The Effect of Outlet Inclination on Two-Phase Flow Splitting in an Equal-Sided Impacting Tee Junction
Bibliographic record
Abstract
Phase-distribution data have been generated for two-phase (air-water) flow splitting at an impacting tee junction with a horizontal inlet and inclined outlets. This investigation also considers the full-separation capabilities of the junction and the effect of the outlet angle of inclination on partial separation at various inlet conditions. A flow loop with the ability to incline the outlets from −90° downward to +90° upward was constructed. The operating conditions were as follows: test-section inside diameter of 13.5 mm, nominal junction pressure (Ps) of 200 kPa (abs), near ambient temperature (Ts), inlet superficial gas velocities (JG1) ranging from 2.0 to 40 m/s, inlet superficial liquid velocities (JL1) ranging from 0.01 to 0.18 m/s, mass split ratios (W3/W1) from 0 to1.0 and inlet flow regimes of stratified, wavy, and annular. The data reveal that the degree of maldistribution of the phases depended on the inlet conditions, the mass split ratio at the junction, and the inclination angle of the outlets.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
