| 摘要 |
<p>The invention relates to a device for determining the heat transfer coefficient between a fluid and a wall at a point PN of a surface of the wall in contact with the fluid, characterised in that said device includes: a measurement device (DT) which measures at least two temperature values TC1 and TC2 of the wall and a temperature value TF of the fluid; and a computer (C) that includes: a) a first means for calculating, based on the temperature values TC1 and TC2, a temperature value TP of the wall and a heat flow rate F given by the equation: F = - ? grad (TC1 - TC2), where ? is the thermal conductivity of the wall, and b) a second means for calculating, according to the fluid temperature TF, the mean temperature TP and the heat flow rate f, the heat transfer coefficient h being in the form of: h = f / (TF - TP).</p> |
