水锤单管计算源程序，与瞬变流一书中的第一程序相对应-waterhammer program

在计算流体力学中，多项流中有相变时，基于温度的相变UDF-Mass based on the temperature of the phase change in the UDF

马氏体相变温度计算程序源代码，值得推荐，大家下载-Martensitic transformation temperature calculation program source code, it is recommended, you try to download

本程序应用于fluent数值模拟蒸发相变过程，由于fluent软件内不含所需的蒸发模型的方程，需要加入用户自定义（UDF编程）计算，改程序即为蒸发相变模拟编程。-This procedure is applied to the evaporation phase transition fluent numerical simulation process, since the evaporation model equations contain the desired fluent softw
