Innovative Training Mode Based on Scientific Research Platform——Simulation of Computational Cluster Environment Thermodynamics

现今对于人才的培养强调创新,通过对计算集群热力学模拟,在理论知识掌握的基础上,利用有限元仿真软件,结合实际情况,对整体集群的房间热分布情况进行模拟。尝试结合房间具体情况,设置初始条件和边界条件,利用ANSYS CFX有限元仿真软件模拟柜式与中央式两种空调模型下的集群房间温度场,得出房间整体温度随时间的演化,给出制冷效率的最佳方案。基于热力学仿真软件,不但对物理模型准确建立,而且熟练划分模型网格,通过有限元计算热力学分布。从这些计算结果可以看出,通过实际课题,设置相关难度,例如在模型建立和网格化分的过程中优化的问题,这些对于学生科研训练有相当大的帮助。另外,这些结果对空调样式的选择与安装设计有着重要的现实意义与参考价值。

Nowadays, innovation is significant of the cultivation of talents. This project, based on the platform of scientific research, payed more attention to the students’ practice of innovation. On the basis of mastering the theoretical knowledge, this project skilled in using finite element software to simulate the thermal distribution of the room in combination with the actual situation through the research on the thermodynamic simulation of computing cluster in the Southwestern Institute of Physics （SWIP）. In this paper, the relevant parameters were set in order to research room specific circumstances. Then we set the initial condition and boundary condition. Finally, we have simulated temperature field of the cabinet form air-conditioner and central air-conditioner styles by ANSYS CFX. The evolution of temperature with time was obtained, and the optimal scheme of cooling efficiency was given. Based on the thermodynamic simulation software, not only the physical model was established, but also the model grid was divided masterly to calculate thermodynamic distribution by the finite element method. From these results, the actual project that sets the relevant difficulty, such as in the process of modeling and meshing the problem is very beneficial for training ability of student scientific research. In addition, these results have important practical significance and reference value about air conditioning styles’ choice, installation and design.
