摘要

:了解 0 至 100 °C、0 至 100% 相对湿度范围内潮湿空气的导热率对各种应用都具有重大意义。然而，直接测量气态物质的热导率具有挑战性。我们使用改良版的 3-omega 方法证明，在合理误差范围内直接测量是可行的。

Measuring the Thermal Conductivity of Humid Air over a Broad Temperature and Water Content Range

: The knowledge of the thermal conductivity of humid air between 0 and 100 ◦ C and 0 and 100% relative humidity is of great interest for various applications. However, direct measurement of the thermal conductivity of gaseous substances is challenging. Using an adapted version of the 3-omega method, we show that direct measurement is possible within a reasonable error limit.
