Abstract

The heat transfer coefficients of flow boiling in a small semi-circular channel of plate once-through steam generator were tested by experimental method in this paper. Based on the experimental data, the numerical simulation of flow boiling in the semi-circular channel was carried out using STAR-CCM + software. The numerical models are the homogenous flow model, the Rohsenow model and the two-fluid model. The heat transfer coefficients of homogenous flow model are lower than the experimental results. The heat transfer coefficients of Rohsenow model and experiment are in good agreement.

板式直通式蒸汽发生器半圆形小通道内沸腾流动的实验与数值研究

摘要

本文通过实验方法对板式直通式蒸汽发生器的小半圆形通道内流沸腾的传热系数进行了测试。根据实验数据，使用STAR-CCM +软件对半圆形通道内的沸腾进行了数值模拟。数值模型是均质流动模型，Rohsenow模型和二流体模型。均匀流动模型的传热系数低于实验结果。Rohsenow模型的传热系数与实验吻合良好。
