Abstract

The article elucidates the characteristic features of heat transfer from a fast-response heater probe to a pulse-heated liquid solution in the heat conduction mode. The heating time was 10 ms; the heat flux density increase was up to 10 MW/m² by order of magnitude. The experiments confirmed the conclusion by L.P. Filippov on the appearance of additional (with respect to the additive values) thermal resistance of liquid with the addition of a second component to it. The verification of the conclusion based on a new material relying on the substantial expansion of the range of variation of the excess volume and temperature, including in not fully stable states, briefly superheated relative to the temperature of liquid-vapor and/or liquid-liquid equilibrium. The results indirectly indicate the excess volume at the initial temperature of the solution as a key factor determining the value of its additional thermal resistance in the superheated state.

过热混合物的热传导：与过量体积的关系

摘要

本文阐明了热传导模式下从快速响应的加热器探头到脉冲加热液体溶液的传热的特征。加热时间为10 ms；热通量密度增加高达10 MW/m ² 按数量级。实验证实了 LP Filippov 的结论，即在液体中添加第二种成分后会出现额外的（相对于附加值）热阻。结论的验证基于一种新材料，该材料依赖于过量体积和温度变化范围的显着扩大，包括在不完全稳定的状态下，相对于液-气和/或液-液的温度短暂过热平衡。结果间接表明溶液初始温度下的过量体积是决定其在过热状态下附加热阻值的关键因素。
