| Based on transient heat transfer theory, temperature stabilization time was analyzed by lumped parameter method and finite element method respectively. The calculation formula of lumped parameter method and is application limitation was put forward. Considering the effect of wind speed, sample medium, and outer surface, the method to determine the heat transfer coefficient between sample medium and outer surface was studied. The results of lumped parameter method were compared with that of finite element method, and it was founded that they are consistent with each other. |
