Numerical analysis of the influence of a circular fin with different profiles on the thermal characteristics in a ceramic tube of heat transfer equipment

摘要

The temperature distribution for steady-state heat transfer and the thermal stresses induced by a temperature difference in a silicon carbide (SiC) ceramic tube with a circular fin are studied in this paper. The finite element method was used to compute the temperature and the stress fields. The influence of a circular fin with different profiles on the temperature and thermal stresses has been investigated. It is found that the fin diameter is a significant parameter affecting the temperature and stress distributions.
