堆积床相变储热系统中径向孔隙率振荡分布对热性能的影响 Article

由于具有较高的储热能力和传热速率,堆积床相变储热被认为是一种很有潜力的储热方法。在堆积床中,壁面效应会影响相变胶囊的填充结构,从而引起径向孔隙率的振荡。本研究建立了一个基于球体实际堆积过程的三维堆积床相变储热模型,以描述径向孔隙率的振荡分布,并分析了其内部的流动和传热情况。通过在堆积床中沿径向不同位置截取圆柱面,揭示了相变胶囊的排列与径向孔隙率之间的对应关系。径向孔隙率的振荡分布导致换热流体速度呈不均匀分布,因此相变材料的径向温度分布和液相分数分布进一步受到影响。此外,本文讨论了不同的无量纲参数(如管与胶囊的直径比、雷诺数和史蒂芬数)对换热流体和相变材料径向特性的影响。结果表明,不同的直径比对应于不同的径向孔隙率分布。此外,随着直径比的增加,在壁面附近区域换热流体速度显著变化,而中心区域换热流体速度的不均匀性将减小。雷诺数和史蒂芬数对换热流体的相对速度分布有轻微影响,而更高的雷诺数可导致速度成比例地提高,史蒂芬数的增加可加快堆积床相变储热系统的储热过程。

This paper introduces the basic conception of information fusion and some fusion diagnosis methods commonly used nowadays in rotating machinery. From the thought of the information fusion, a new quantitative feature index monitoring and diagnosing the vibration fault of rotating machinery, which is called distance of information entropy, is put forward on the basis of the singular spectrum entropy in time domain, power spectrum entropy in frequency domain, wavelet energy spectrum entropy, and wavelet space feature entropy in time-frequency domain. The mathematic deduction suggests that the conception of distance of information entropy is accordant with the maximum subordination principle in the fuzzy theory. Through calculation it has been proved that this method can effectively distinguish different fault types. Then, the accuracy of rotor fault diagnosis can be improved through the curve chart of the distance of information entropy at multi-speed.
