基于传热分区的直流蒸汽发生器换热性能仿真
Heat transfer performance simulation of once-through steam generator base on partition
摘要
Abstract
For the complexity of flow and heat transfer in the once-through steam generator secondary side, the secondary side is divided into preheating section, subcooled boiling section, saturated nucleate boiling section, forced convective evaporation section, lacking of liquid section and superheated section in order to accurately research the internal thermal parameters of spatial distribution rules. The one-dimensional homogeneous flow mathematics model of once-through steam generator is built base on the distribution parameter method. The independent developed MATLAB simulation program can be used to automatically piecewise calculate for once-through steam generator. The results show that the model can accurately predict the wall temperature soaring amplitude and location and the length of heat transfer areas in different conditions based on partition. The poor working area of once through steam generator can be forecasted. The results can provide theoretical support for preventing tube burst accident of once through steam generator.关键词
