摘要

在临界点附近时，超临界水的热膨胀系数很大，随着压力的升高，拟临界点的热膨胀系数迅速下降，拟临界点的热膨胀系数是计算临界相变转换数的基础，对于分析超临界压力下的流动不稳定性非常重要。因此，计算超临界水在拟临界点的热膨胀系数，对于了解和掌握超临界水堆中能量的转换或热量传递非常重要。运用MATLAB曲线拟合工具箱，对超临界水的拟临界点的膨胀系数进行了拟合回归分析。拟合得出了超临界水的拟临界点的热膨胀系数的计算公式。该公式具有结构简单易于计算的特点，最大绝对误差为0.20 K

-1

，最大的相对误差为0.19%，计算精度满足工业研究与分析的要求。

Abstract

Background:

The supercritical water thermal expansion coefficient is very large when the reactor is approaching the critical point

but drops rapidly with the increase of pressure. The pseudo-critical thermal expansion coefficient is the basis for calculation of the critical phase transition transformation number which is of great importance in the analysis of flow instability of supercritical pressure water

therefore its calculation is very important to understand and master the conversion of energy or heat transfer in supercritical water reactor.

Purpose:

This study aims to derive a fitting formula for direct calculation of the pseudo-critical expansion coefficient. It is useful for thermal-hydraulic program analysis.

Methods:

First of all

the pseudo-critical temperature need to be calculated

then a regression analysis for the pseudo-critical thermal expansion coefficient of supercritical water is fitted by using MATLAB curve fitting toolbox. The fitting calculation formula about the pseudo-critical thermal expansion coefficient is derived from those fitting data in the form of combination formula.

Results:

The calculation result is continuous smoothness with maximum absolute error no more than 0.20 K

-1

and the biggest relative error is 0.19%.

Conclusion:

The formula is simple in structure and easy to calculate with high efficiency

and the calculation precision meets the requirements of industry research and analysis.
