家用燃气灶热性能敏感度分析

Sensitivity Analysis of the Thermal Performance of Domestic Gas Oven

用基于蒙特卡洛法的局部敏感性指标对家用燃气灶热性能进行敏感度分析,求得的结果与全局敏感性指标的结果相吻合。对于热负荷,试验时间和低热值对测量结果的不确定度的贡献最大,其他因素可忽略不计;对于热效率,耗气量和低热值对测量结果的不确定度的贡献最大,其他因素也可忽略不计。这种指标计算简单,易于理解,稳定性好。

Sensitivity analysis based on Monte Carlo method is used to analyze the thermal performance of domestic gas cooker, and the result is consistent with the result of global sensitivity index. For thermal load, test time and low calorific value contribute most to the uncertainty of measurement results, and other factors can be neglected. For thermal efficiency, gas consumption and low calorific value contribute most to the uncertainty of measurement results, and other factors can also be ignored. This index is simple and easy to understand and stability is good.
