Evaluation of Uncertainty in Measurement of the Super-heated Steam Density based on Monte Carlo Method

Abstract

In this paper, Monte Carlo method (hereinafter referred to as MCM) is used to evaluate the uncertainty of super-heated steam density. Through more than 800k simulation tests using the MCM ALCHIMIA software, the probability density function, coverage probability and coverage interval of the super-heated steam density are obtained, and the graphic shape of probability density function is analysed. In the process of evaluating the measurement uncertainty of superheated steam density, it is not rigorous to blindly define its probability distribution as uniform distribution. At the same time, when evaluating the uncertainty of superheated steam density, the use of gum has inherent shortcomings, and the use of MCM can get the real situation more accurately.
