温度场数值模拟后置处理中等温线的算法研究

The Methodical Research of Equal Temperature Lines in the Numerical Simulative Post-processing of the Temperature Field

应用场论和映射法对温度场等温线的算法进行了分析研究。通过数量场方向导数、梯度等理论 ,建立了求取等温线的算法 ,通过母单元与子单元之间一一对应关系 ,建立了间接绘制等温线的算法。

The present work analyzed the methods of equal temperature lines in the temperature field by the field theory and mapping.With the theory of directional derivative and gradient of the numerical field,it set up the method to acquire equal temperature lines,and with the one to one correspondence between the son elements and the mother element,it gave the method to build the equal temperature lines indirectly.
