| 英文摘要: |
| Restricted by the size and structure of the temperature and humidity standard box, the ventilation psychrometer will have a great impact on the humidity field in the verification process. A three-dimensional steady-state calculation model with equal proportion was established. The component transfer model and SIMPLE algorithm were used to simulate the humidity field in the verification process. The distribution characteristics of the humidity field were analyzed, and the scientificity and accuracy of the simulation results were verified by experiments. |
