摘要

吸附蓄热是实现太阳能高效热利用最有前景的方式之一。然而，现有的反应器层面传热传质理论关注于反应器内单一物理过程的演变，无法揭示多物理参数间非线性耦合机理。本工作以沸石-水蒸气为吸附工质对，建立吸附蓄热反应器的数值模型，分析反应器内多物理场的演变过程，提出多参数吸附“反应波”模型。研究结果表明：吸附过程中，反应器内存在多参数“反应波”现象。反应器内吸附剂的吸附速率、轴向温度梯度与轴向浓度梯度均呈现出波特性，三种“反应波”分别对应于吸附反应过程、传热过程与传质过程。分析“反应波”在反应器内的移动过程，阐明反应器热输出特性。当反应器内吸附剂的堆积高度大于反应波波长时，反应器才具有稳定输出温度。基于无量纲波形分析明确多参数吸附“反应波”波形间的定量联系。

Abstract

The adsorption thermal energy storage (ATES) is one of the most promising approaches to realize the efficient thermal utilization of solar energy. However

the existing reactor-level heat and mass transfer theories focused on the evolution of individual reactor physical processes fail to elucidate the mechanism behind nonlinear dependencies between multiple physical parameters. In this study

a numerical model of an ATES reactor using zeolite-water vapor as the adsorption working pair was established. The evolution of multi-physics fields within the reactor was analyzed. The multi-parameter adsorption reaction-wave model was proposed. The results indicate that a multi-parameter reaction-wave arose within the reactor during the adsorption process. The adsorption rate of adsorbent

axial temperature gradient and axial concentration gradient within the reactor all exhibited wave characteristics

corresponding respectively to the adsorption reaction

the heat transfer and the mass transfer. The movement of reaction-wave across the reactor was analyzed to elucidate the reactor thermal output characteristics. When the packed height of adsorbent in the reactor exceeded the wavelength of the reaction wave

the reactor operated at a stable output temperature. Correlations between multi-parameter adsorption reaction waveforms were quantified using the dimensionless waveform analysis.
