研究了静态饱和超流氦中不同厚度、孔隙率和孔径的多孔介质的传热特性。对于大孔径，在纯Gorter-Mellink方案中使用弯曲度概念分析数据。结果表明，在所研究的温度范围内，弯曲度是恒定的。对于较小的孔径，分析表明，在朗道状态下，渗透率与温度有关。在中间状态下，包括朗道和Gorter‐Mellink状态的模型预测了10%以内的恒定弯曲度，但福尔斯在整个温度范围内正确预测了实验数据。
Heat transfer through porous media in static saturated superfluid helium is investigated for porous media with different thickness, porosity and pore size. For large pore diameter, data are analyzed with the tortuosity concept in the pure Gorter‐Mellink regime. It is shown that the tortuosity is constant over the temperature range investigated. For smaller pore diameter, the analysis reveals that the permeability is temperature‐dependent in the Landau regime. In the intermediate regime, a model, including Landau and Gorter‐Mellink regime, predicts a constant tortuosity within 10% but falls short predicting correctly the experimental data over the entire range of temperature.
