Abstract
Abstract This study numerically investigated fluid flow and heat transfer characteristics of conical Taylor–Couette flow with a radial temperature difference. The computational conditions were limited to a moderate Reynolds number ( Re ) regime. The Rayleigh number Ra , which characterizes the buoyancy‐driven flow, was varied using two types of fluids: water for the higher Ra (= 61,437.7) and 40 wt.% glycerol aqueous solution for the lower Ra (= 18,373.2). The flow pattern of the conical Taylor–Couette flow was confirmed to be significantly affected by Ra . In particular, at the higher Ra tested ( Ra = 61,437.7), large‐distorted Taylor cells were observed at the highest Re within the computational conditions of this study. Additionally, the time‐series data of the velocity fluctuation were analyzed through continuous wavelet transform analysis, and consequently, logarithmic expectation and information entropy were obtained. The results indicated that the velocity fluctuation exhibited a fractal structure. Furthermore, the area‐ and time‐averaged Nusselt numbers ( Nu t ) of the conical and cylindrical systems were compared based on the power consumption per volume. The conical system achieved comparable heat transfer performance with a substantially lower power input under higher Ra , demonstrating its superior energy efficiency.

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
