Abstract

The modeling of atmospheric ice accretion on duplex cylinders received a limited attention, with modeling carried by Wagner and Qing et al. The publicly available experimental data about the ice accretion on the duplex cylinders is limited to experiments of Qing et al. and Veerakumar et al. When comparing the data of Wagner and Qing et al. with the results of Veerakumar et al., the major difference is the airflow behavior in the wake of the windward cylinder, the extent of the wake and recirculation bubble, and the velocity distribution in the wake. Thus, its needed to study the effect of the turbulence model on the airflow behavior of duplex cylinders, with focus being the behavior of the wake of the windward cylinder. This study reports the simulation results of the complex airflow behavior of duplex circular cylinder bundle obtained using several turbulence models employed by commercial CFD code.

双圆柱的气流特性研究
双圆柱体上大气冰堆积的模拟受到了有限的关注,由Wagner和Qing等人进行了模拟。关于双筒冰的吸积的公开实验数据仅限于Qing et al.和Veerakumar et al.的实验。将Wagner和Qing等人的数据与Veerakumar等人的结果进行对比时,主要的差异在于迎风圆柱尾迹中的气流行为、尾迹和再循环气泡的范围以及尾迹中的速度分布。因此,有必要研究湍流模型对双柱体气流特性的影响,重点研究迎风柱体的尾迹特性。本文报道了利用商业CFD程序中几种湍流模型对双圆柱束复杂气流特性的模拟结果。
