Uncertainty Estimation in the Determination of Thermal Conductivity of 304Stainless Steel

摘要

The thermal conductivity of 304 stainless steel has been estimated from transienttemperature measurements and knowing the volumetric heat capacity. Sensitivity coefficients were used to guide the design of this experiment as well as to estimate the confidence interval in the estimated thermal conductivity. The uncertainly on the temperature measurements was estimated by several means, and its impact on the estimated conductivity is discussed. The estimated thermal conductivity of 304 stainless steel is consistent with results from other sources.
