摘要
为计算发动机内流系统、管网等复杂系统,提出了节点残量修正算法在工程计算中的通式。推导出了节点压力、温度残量修正算法具体计算公式,并在此基础上将算法编程,提高了算法的实用性和可操作性。进行了算例验证,算法收敛性和稳定性很好,并考察了压力、温度松弛因子对算法的影响。
In order to compute complex systems like engine＇s internal system and network, the general formula in the project calculating which use the method of gradually reducing the remnants is presented. The equations set of pressure and temperature remaining amendment method is deduced. On the base of this equations set this method is programmed. This method＇s practicability and maneuverability are enhanced. By means of computing one network, the calculating process was steady and converges well. The influence of temperature and pressure relaxation genes in the technique＇s convergence were also studied.
