摘要
利用Visual Fortran及Visual Basic对天然气压缩过程和膨胀过程中的过程指数进行了计算分析。通过分析计算,得出了过程指数与温度、压力的关系,同时解决了通过查图得到过程指数的不足,提高了计算的精度和效率。
Utilizing Visual Fortran and Visual Basic,polytrophic exponent of natural gas in compression and expansion was calculated.By mathematical analyzing,the relationship between polytrophic exponent and temperature and pressure was get,the shortage of getting polytrophic exponent by looking diagram was solved,and the precision and efficiency were risen.
