if you simplify the model to be shell, thermally it can be taken as a thermal interface resistance.
if you simplify the model to be beam, then you assume the temperature is uniform in cross-section area, e.g. temperature changes only along the beam direction.
if you simplify the model to be a volume, then you assume the temperature is uniform inside the body, e.g., a high thermal conductivity metal ball in a convective environment. |
