摘要
通过热力学关系分析和导出vdW气体的比热容比与音速的关系式,将它与实验测定的数值以及理想气体比热容比进行对比分析,并运用Matlab仿真技术绘制出比热容比与温度的关系曲线,进而说明vdW气体比热容比与实际气体比热容比吻合的程度好于理想气体的比热容比.
The relation between specific heat capacity ratio of vdW gas and sonic speed is analyzed and derived by thermodynamics relation and is compared, analyzed with the value from experimental determination and specific heat capacity ratio of ideal gas. The relation curve between specific heat capacity ratio and temperature is developed by using simulation technique of Matlab and the reasons why the coincident degree between specific heat capacity ratio of vdW gas and real gas is better than the specific heat capacity ratio of ideal gas are provided in the paper.
