| 1 | 强制对流条件下不同传热流体对含相变材料柱形容器放热性能的影响显示文摘本文采用数值模拟方法研究了强制对流条件下不同传热流体对含相变材料柱形容器的放热性能的影响。以空气、氢、水和含氧化铝颗粒的纳米流体作为传热流体,同时考虑了含相变材料(PCM)区域的结构变化,采用有限元法进行求解。研究了不同传热流体类型、雷诺数(100~300)和含PCM区域结构变化(h_(x)在0.01d_(1)~0.65d_(1),h_(y)在0.1h_(1)~0.4h_(1))下不同相的换热动力学特征。研究发现,换热流体类型对放热时间影响较大,以空气为换热流体时相变完成时间比以空气为换热流体时的长10倍以上,而以纳米流体为换热流体时的时间最短。当含PCM区域减小时,放热时间缩短。含PCM区域的结构导致涡流的形成,这使在内筒的半径和高度最大处的性能下降。当内筒半径从h_(x)=0.35d_(1)增加到h_(x)=0.45d_(1)时,放热时间延长约12%。在不同雷诺数下,PCM的温度和液体组分的动态特性均受雷诺数的影响,与最小雷诺数相比,最大雷诺数下的PCM的放电时间缩短了48%左右。 | SELİMEFENDİGİL Fatih ŞİRİN Ceylin ÖZTOP Hakan F | 2021 | Journal of Central South University2021，28，11： | 2 |

| 7 | Thermal management of nanoliquid forced convective flow over heated blocks in channel by using double elliptic porous objects显示文摘Effects of using nanoliquid and double porous elliptic objects on the flow separation and convective heat transfer control for flow over multiple heated blocks in channel are numerically investigated by using finite element method.Spherical,brick,blade and cylindrical shaped alumina particles are used in water up to solid volume fraction of 2%.Impacts of Reynolds number(50≤Re≤500),permeability of the porous ellipses(10^(-5)≤D_(a1)≤5×10^(-2) and 10^(-5)≤D_(a2)≤5×10^(-2)),aspect ratio of the ellipses(0.25≤AR_(1)≤1.5,0.25≤AR_(2)≤1.5),distance between the ellipses(0.2H≤sx≤1.6H)and distance of the first ellipse from inlet(-H≤mx≤H)on the hydro-thermal performance are explored.The highest performance improvement is obtained by using the cylindrical shaped particles in the base heat transfer fluid at the highest solid volume fraction and the amount of heat transfer enhancement are 33%and 40.5%for hot blocks while negligible pressure drop is observed.Varying the aspect ratio of the ellipses in the perpendicular direction to the flow,up to 25%and 30%heat transfer increment are obtained for hot block with slight rise of pressure coefficient.However,when varying the horizontal location of the porous ellipses in the channel and permeability of them,there is considerable rise of pressure drop.Variation of the average heat transfer from the hot blocks with varying permeability of the ellipses are obtained as 32%and 25%.Successful hydro-thermal performance estimation results are achieved by using artificial neural networks with feed-forward network architecture of 1 hidden layer and 17 neurons. | Fatih Selimefendigil Hakan FÖztop | 2021 | Propulsion and Power Research2021，10，3： | 1 |
| 8 | 纳米流体强制对流过程中充填相变材料的三角形弹性壁通气腔内的相变动力学显示文摘本文研究了在层流状态下纳米流体强制对流时三角形弹性壁通气腔内的相变过程动力学。采用有限元方法探讨了雷诺数(Re)、柯西数(Ca)和腔口尺寸对流场和相变动力学的影响。研究发现,Re、Ca和腔口尺寸的变化对进气道下流动再循环和相变动力学有一定的影响。当Re从100增加到200时,相变时间(TF)先缩短后延长。在Re=100时,混合纳米流体相变速度快,相变时间降低约26%。当Ca为最大值时,相变时间减少了12.5%。腔口尺寸对相变有负面影响,而腔口尺寸的增大使相变时间增加了19%。 | SELİMEFENDİGİL Fatih ÖZTOP Hakan F Nidal ABU-HAMDEH | 2023 | Journal of Central South University2023，30，11： | 1 |
