摘要
本文采用高次插值函数推导出具有三子域的分区均质平面热传导边界元方程,然后针对195型柴油机缸盖鼻梁区温度场实际问题进行了数值分析,结果表明本文推导出的分区等参边界元方程具有较强的通用性,用于分区均质热负荷问题的分析是十分有效的。
In this paper, three homogeneous subregions boundary element equation with high interpolation function for two dimension heat conduction problem is propsed and then, the temperature field of the bridge zone between valve seats of the cylinder head of 195 type diesel engine is analysed numerically. The results obtained show the subregion boundary element equation with isoparametric element derived in this paper is a powerful method for analysing the heat load of homogeneous subregion bproblems.
