Abstract

fetched live from OpenAlex

R SUM Ce travail se concentre sur la conception et l'optimization d'une sonde d'interfrence base d'anmomtrie thermique utilise pour simultanment mesurer les champs de concentration et de vitesse dans des coulements turbulents.Bien qu'un petit nombre d'investigations prcdentes aient russi effectuer ces mesures avec succs, peu de travail a t fait pour examiner et expliquer les composants ncessaires d'une telle sonde spcialise, qui ncessite qu'un capteur d'anmomtrie thermique soit opr en aval, et quelques micromtres, d'un deuxime.Les effets des rapports de surchauffe, la sparation entre les fils, les diamtres des fils, et les matriaux des fils, sont tudis dans le cadre de cette investigation.Des expriences, effectues dans la rgion non-flottable d'un jet turbulent, rvlent que des mesures de concentration et de vitesse bien russies exigent une sonde d'interfrence contenant (i) deux fils de diamtres diffrents et (ii) une petite distance de sparation, d'environ 10 m, entre les fils.De plus, le fil en amont devrait tre opr un rapport de surchauffe lev et le fil en aval devrait tre opr un rapport de surchauffe assez faible.En comparant les six sondes d'interfrence de conceptions varies construite dans cette thse, une sonde d'interfrence optimale, consistant d'un fil de tungstne de 5 m, en amont d'un fil de platine-rhodium de 2.5 m, a t identifie.La prcision de cette sonde a t valide contre des coulements de conditions connues, des tudes prcdentes, et les mesures d'une sonde fil-chaud, dont la prcision a dj t tablie.

Full frame distilled prediction

Teacher imitation

Not 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.
