摘要
本文根据流体力学原理和锅炉水动力计算方法的基本原则,提出了一种可以直接计算自然循环锅炉对流管束回路中每根单管水动力特性的自然循环锅炉水动力数值计算新方法,即水动力压差分析法。推导得出了基于该方法的水动力数值计算的基本方程组,给出了其数值求解方法,并对其收敛性进行了深入分析。
In this paper, based on the hydromechanics and the principle for hydrodynamic calculation of boiler, a pressure difference analysis method for the numerical calculation of hydrodynamic characteristic of boiler with natural circulation is presented, which can calculate the flux of every tube in convective tube loop of the boiler. The equations of the pressure difference analysis method and their solving procedure are deduced and the convergence of the equations are analyzed in detail.
