Design of the Virtual Experiment for Condenser Thermodynamic Characteristics Based on Web

基于Web的凝汽器热力特性虚拟实验,以某660 MW超超临界机组的凝汽器系统为原型,采用两相流仿真模型作为虚拟实验底层计算模型,准确模拟凝汽器系统的参数变化和热力过程的动态特性,直观形象地展示了凝汽器的特性曲线,填补了学生脱离实物设备无法实验的空白。该虚拟实验改变了实验教学方式,改善了教学效果;培养了学生对凝汽器系统的认识和理解能力,提高了学生的工程实践能力以及创新能力。

The virtual experiment of condenser thermodynamic characteristics based on Web,takes the condenser system of a 660 MW ultra-supercritical unit as the prototype and the two-phase flow simulation model as the underlying calculation model of the virtual experiment,accurately simulates the parameter changes of condenser system and the dynamic characteristics of thermodynamic process.It shows the characteristic curve of the condenser visually,and fills the blank that students cannot experiment without physical equipment.This virtual experiment changes the experimental teaching method and improves the teaching effect.It cultivates students'understanding ability of the condenser system and improves their engineering practice and innovation abilities.
