Said method, which aims to determine a quantity representative of the thermal resistance of a separation wall between a first medium and a second medium, comprises the following steps: -over at least two successive time periods Dk corresponding to different heating powers Pk for heating the first medium, carrying out a measurement campaign measuring the heat flow through the wall qk and the temperature in the first medium T1k at short time intervals, in addition to the determination of the temperature in the second medium T2k at short time intervals; -determining the value of the quantity representative of the thermal resistance of the wall, by converging: a thermal model expressing the time variation of the temperature in one medium separated from another medium by a wall, depending on the heat flow through the wall, the temperature in the other medium and physical parameters of the wall from which the quantity representative of the thermal resistance of the wall can be calculated; and the measured change T1k in temperature in the first medium as a function of time. |
