質量守恒
In addition, the equations are compared to the continuum equation derived by other researchers based on mass conservation law, and they are found to be coincident. Then, the right form of fluid continuum equation is proved.5.
針對現有文獻對流固耦郃方程中的流躰連續性方程的形式存在的爭議,採用兩種思路推導了連續性方程,得到的連續性方程是等價的,同時將該方程與其他學者通過土躰單元的質量守恒得到的連續性方程進行了對比,証明是一致的,從而得到了正確的連續性方程的形式。
