摘要
自动喷水灭火系统格栅状管网(下称"格网")的形式较为复杂,准确且高效的水力计算是其推广应用的前提。"格网"的水力计算与城市给水管网平差类似,采用节点方程法较为合适。基于方程组对应的系数矩阵为大型稀疏对称正定矩阵,对系数矩阵的生成算法、储存算法和分解算法进行了优化,规避了零元素的储存和运算,有助于提高计算效率。
The form of gridded sprinkler system is complex, accurate and efficient, hydraulic calculation is the premise of its popularization and application. Gridded sprinkler system hydraulic calculation is similar to the calculation of urban water supply networks, and node equations method is more suitable. Based on the coefficient matrix of equations is large sparse symmetric positive definite matrix, the paper optimizes the generation algorithm, storage algorithm and decomposition algorithm of the coefficient matrix, non-storage and non-operation of zero elements helps to improve computational efficiency.
