Impact of Nearby Adiabatic and Isothermal Barriers on the Thermal Characteristics of a Vertically Oriented Pot-Core Magnetic Component
Bibliographic record
Abstract
The coupled problem of estimating the temperature rise due to the winding and core loss in a vertically oriented magnetic component is considered. The principle contributions in this paper are two-fold: 1) the coupling between the losses and thermal problems for the component is addressed accounting for the effects of nearby barriers and 2) the complication that the convection coefficient is not known accurately is overcome by means of solving a coupled electrothermal-air flow problem in order to characterize heat transfer to the ambient surroundings. It is shown that the coupling between the loss and temperature in the magnetic material has negligible effects on the temperature since the deviation in temperature is not more than 13% at worst if the loss is considered constant for different barrier-to-core distances. The convection coefficients of the core's top and side surfaces are shown not to be significantly influenced by the boundary condition imposed on the barrier. The boundary conditions substantially affect the temperature by introducing an additional path for heat transfer. Additionally, the contribution of radiation is found to be roughly 50% of the total loss regardless of the barrier height and distance and its boundary condition

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.
