基于节点压能的网络分风算法

Networks Dividing Wind Algorithm Based on Node Press-energy

网络分风算法一直是进行通风网络解算研究的重要内容,运用计算机进行网络解算的快慢受到分风算法的限制。传统的回路法、节点法由于要进行回路或迭代加速系数的计算,程序复杂,对于大规模网络计算时间较长。采用基于节点压能的网络分风算法避开了回路和迭代加速系数的计算,具有风量初始值任选,迭代次数少等优点,结果精度符合实际要求,对通风网络解算研究具有指导作用。

The algorithm of network dividing wind is important content for studying ventilation network calculation. The speed of calcu- lating network by computer is limited by dividing wind algorithm. The calculation of traditional loop and node method with complex pro- cedure needs long time to compute large - scale network due to the calculation of loop or iteration acceleration coefficient. The network dividing wind algorithm based on the node press - energy, with advantages of opting initial value of amount wind and less iterations, a- voids the calculation of loop and iteration acceleration coefficient. The accuracy of the result is met for the actual requirements ; it has a guiding role for ventilation network calculation research.
