1采用Fe_(2)O_(3)/水纳米流体强化翅片管壳换热器的传热显示文摘为了优化效率和减少能量损失,需要对传热机理及热性能进行全面研究。在基液中加入不同的纳米颗粒可提高热交换器的热性能。设计了一种翅片管壳式换热器,以体积浓度分别为1%、1.5%、2%的Fe_(2)O_(3)/水纳米流体作为换热流体,研究不同体积浓度的纳米流体对传热的影响,并将所得结果与纯水作为换热流体结果进行比较。采用ANSYS Fluent软件对传热过程进行数值模拟。数值模拟结果表明:纳米流体可成功应用于换热器中,提高Fe_(2)O_(3)纳米颗粒的体积分数可以获得更大的热能,而不会产生明显的压降。此外,当纳米流体中Fe_(2)O_(3)的体积分数为2%时,其传热速率提高率最高,为19.1%。AFSHARI Faraz SÖZEN Adnan KHANLARI Ataollah TUNCER Azim Doğuş 2021Journal of Central South University2021,28,11:2

13不同参数对热泵性能影响的实验研究显示文摘在热泵领域,有许多影响装置性能和效率的参数。本研究采用实验方法研究重要参数对热泵性能的影响。在不同工况下,利用实验室热泵装置研究制冷剂类型和充注量、压缩机油黏度、压缩机冷却风扇、二次流体温度和流量等参数的影响。选择不同的制冷剂作为热泵的循环流体。本文在研究不同参数对COP的影响之外,还对其经济性进行了分析。结果表明,制冷剂充注量是影响COP的主要参数之一,添加合适的制冷剂可使系统性能提高11%以上。此外,通过选择低黏度压缩机油,系统性能提高18%。当采用冷却风扇冷却压缩机元件时,系统性能提高超过6%。AFSHARI Faraz SÖZEN Adnan KHANLARI Ataollah TUNCER Azim Doğuş ALI Hafiz Muhammad 2021Journal of Central South University2021,28,11:0
