Abstract
This study deals with heat transfer characteristics in a blazing plate heat exchanger used as a condenser in heat pump hot water heater. In this report, experiments of single channel heat exchanger were carried out by using a pump driven two-phase flow loop. The test section has one path for each fluid, refrigerant and water. The effects of mass flow rate of refrigerant and water, wave height of plate, and setting arrangement, vertical with downward refrigerant flow or horizontal, were examined. HFC134a was used as the refrigerant. Superheated vapor was supplied to the condenser, and heated water. Water was flowing in the counter flow direction. The wall temperature distribution of the refrigerant path was measured by an infrared camera. As a result, it was shown that the lateral temperature distribution for the horizontal arrangement was affected by the wave pattern while that for the vertical arrangement was uniform.

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 it
