Numerical Simulation of Temperature Field in Sample Assembly of Cubic Press
摘要
Abstract
Numerical simulation for the temperature distribution in sample assembly of cubic press was carried out by using the finite-element method with simplified model and boundary conditions.Based on the adjustment of parameters of the models in simulation,the temperature distribution induced by pressure transmission media,shapes of heater and conductive metal ring were discussed in details.The results indicate that the use of zirconia instead of pyrophyllite as the buffer and thermal insulator can elevate the temperature and at the same time lower the thermal gradient in sample area while reducing power consumption.Different shapes of heater will affect on the temperature distribution.In the case of the metal ring being used in assembly,properly increasing the thickness of the ring will be beneficial to obtain desirable temperature distribution.This work could be a useful reference to optimize the design of sample assembly in cubic press for high temperature and high pressure experiments.关键词
