| Abstract: | The veracity of experimental and analytical data for the onset of nucleate boiling (ONB with subcooled boiling in natural circulation was examined using the clustering method of fuzzy mathematics to select the most accurate data.The experimental errors of the ONB data with subcooled boiling in natural circulation were analyzed using membership degree determination and fuzzy judgements to select the coefficients of the experimental formula with a high degree of confidence.The results indicate that the fuzzy mathematics method can be used to more accurately analyze ONB data for subcooled boiling in natural circulation. |
