凝汽器喉部蒸汽流动的三维数值模拟

应用具有超粒子模型的直接模拟蒙特卡罗方法，对汽轮机凝汽器喉部进行区域分解和数学建模，及对具有典型结构的凝汽器喉部蒸汽流动进行了三维数值模拟，重点分析了凝汽器喉部流场的流动分布情况，揭示了喉部流场不均匀性流动特点及其产生原因。

Three-dimensional Numerical Simulation of the Steam Flow at a Condenser Throat Section

With the help of a direct simulation Monte Carlo method incorporating a super particle model and through a domain decomposition and mathematical modeling of a steam turbine condenser throat a three dimensional numerical simulation was conducted of the steam flow at the condenser throat of a specific structure. The simulation of the throat steam flow was undertaken with a focus on the analysis of its flow distribution. As a result, identified were the non uniformity feature of the throat flow field and the underlying cause of the non uniform flow field.
