Uncertainty of Recovering Non-Steady-State Heat Flows Using Thin-Disc Heat Meters

A method is proposed for estimating the uncertainty of recovering non-steady-state heat flows using thin-disc heat meters. The uncertainty arises from the outward flow of heat through the central thermocouple electrode. Results are presented for simulation experiments for different values of electro...

Description
Summary:A method is proposed for estimating the uncertainty of recovering non-steady-state heat flows using thin-disc heat meters. The uncertainty arises from the outward flow of heat through the central thermocouple electrode. Results are presented for simulation experiments for different values of electrode length, diameter, and head-conduction factor.
