| 1 | 过渡SST模型模拟椭圆环形翅片管换热器的传热仿真显示文摘本文对椭圆环形翅片管换热器的热流体特性进行了数值模拟研究。采用过渡SST模型对湍流进行了仿真模拟,研究了气流速度、水平/垂直方向翅片直径比以及翅片密度的影响。仿真结果表明,椭圆环形翅片具有优越的性能。在具有相同传热性能的情况下,环形椭圆翅片的压降仅为圆环形翅片的一半。竖直椭圆环形翅片可能含有比圆环形翅片具有更优的热传导性能。利用相关性系数估算环形翅片的Nu数和压降,相关性系数和模拟结果在压降和传热系数上的最大偏差分别为5.6%和3.2%。为从第二定律的角度进一步阐述椭圆环形翅片的优越性,对归一化熵产生进行了研究。在所有情况下,圆环形翅片的熵产生率均高于椭圆环形翅片的。 | H NEMATI A R RAHIMZADEH WANG Chi-chuan | 2020 | Journal of Central South University2020，27，8： | 2 |
| 2 | Deflection amplification factor for estimating seismic lateral deformations of RC frames显示文摘Different values have been assigned to the ratio of the defl ection amplifi cation factor(Cd) to the response modifi cation factor(R) for a specifi ed force-resisting system in the seismic design provisions while the same application is defi ned for it. An analytical study of the seismic responses of several reinforced concrete frames subjected to a suite of earthquake records performed in this research indicate that the stories' overstrength and stiffness distribution along the structural height can affect local defl ections more than global ones. Therefore, the Cd/R ratio is calculated based on the ratio of both maximum inelastic to maximum elastic displacements and interstory drifts. Due to damage concentration in some specifi c stories, the defl ection amplifi cation factor calculated based on inelastic interstory drifts was larger than that of the inelastic displacements. Consequently, a minimum value of 1.0 is recommended for the Cd/R ratio in order to estimate maximum inelastic drifts. The ratio of inelastic to elastic displacement was generally found to increase slightly along the structural height for the studied RC models. In addition, it was detected that the story damage indices of the studied RC frames decrease when the inverted value of inelastic interstory drift ratios are increased through a(negative) power form. | Maryam Samimifar Asghar Vatani Oskouei Fayaz Rahimzadeh Rofooei | 2015 | Earthquake Engineering and Engineering Vibration2015，14，2： | 2 |
