Impact of Sizing on the Temperature of Automotive Lighting Products
Bibliographic record
Abstract
In this study effect of geometrical size on temperature in automotive lighting units is experimentally and numerically investigated. In the experimental phase a product, which includes a P21W type bulb, with clear polycarbonate (PC) material in rectangular section is used. 5 thermocouples are used for temperature measurements. Numerical investigation is conducted with the same geometry and material properties by ANSYS CFX 12.1. In this investigation flow is assumed to be steady and laminar and 3 dimensional (3D) Navier-Stokes equations are used for calculation. It is observed that numerical results are consistent with experimental measurement in terms of temperatures. In the numerical studies where the effect of geometrical size on temperature is investigated distance between filamenthousing (z1), distance between filamenthousing side surface (y) and distance between filamentlens (x) are examined. It is observed that the greatest temperature decline is observed when z1 is increased. y is the least effective one on temperature among investigated parameters. The greatest temperature drop for lens is obtained by change in x.

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.
