摘要/Abstract

摘要： 为降低数值仿真中热分析模型的建模难度、减少网格数量、节约计算成本,提出利用基于网格优先级建模方法和多级网格划分算法对采用微小流道液冷散热方式的有源相控阵天线模型进行热仿真分析。其中多级网格算法在不改变模型内部的网格数量,可对天线复杂部件进行贴体网格划分,明显提高网格质量。通过仿真计算和实验结果表明,该分析方法可获得天线关键部件的温度和压力分布。在保证高精度计算条件下,该建模方法和网格划分方法可提高计算效率,具有一定的工程应用价值。

Abstract: The grid priority modeling and multi-level meshing techniques are applied to analyze the thermal properties of the active phased array antenna with the micro/mini channels cooling method for simplifying modeling process, reducing the mesh quantity and saving the cost of computation effectively. The multi-level meshing technique can refine the mesh near the boundary of the complex components significantly without changing the mesh quantity in the model, which improves the mesh’s quality obviously. Through the thermal simulation and experiment measurement of the antenna, the temperature and pressure field are obtained. It is proved that the addressed approach can advance the calculation efficiency and better simulation accuracy, which has an important engineering application value.

Key words: grid priority modeling technique, multi-level meshing technique, micro/mini channels, active phased array antenna, thermal simulation
