平板上挡板前后涡核位置的测量

在水洞中用氢气泡法在平板上挡板前后的涡核位置进行了测量。本试验旨在确定挡板高度及其雷诺数对涡核装置的影响，结果表明，（ａ）对于单个挡板情况，涡核离开平板的高度和涡核与挡板的距离将随着挡板的高度增加而增加，但涡核的高度和距离与挡板高度的比例随挡板高度的增加而降低；（ｂ）对于两个挡板情况，挡板的高度和挡板之间的距离对涡核位置的影响是主要的。     

Mathematical description of the NaK model for MASTER-2005

The release of NaK droplets has been modeled for the new version of the European Meteoroid and Space Debris Terrestrial Environment Reference model MASTER-2005. Previously published versions of the model have been revised. The parameters of the model are introduced and discussed. NaK droplets consist of eutectic sodium–potassium alloy and have been released during RORSAT reactor core ejections. They contributed to the space debris environment in the centimeter and millimeter size regime. Sixteen nuclear powered RORSATs launched between 1980 and 1988 activated a reactor core ejection system in Sufficiently High Orbits (SHO), mostly between 900 and 950 km altitude. The core ejection caused an opening of the primary coolant circuit. The liquid coolant has been released into space during these core ejections. The outflow is considered as a discrete event for each of the sixteen core ejections in total. The NaK coolant has been forming droplets up to a diameter of 5.5 cm. NaK releases are restricted to a very narrow region near 65° inclination. This paper gives the parameters of the NaK release model as it is implemented in MASTER-2005. The quantitative values of all model parameters including characteristic diameter and uniformity parameter are presented. The ratio of the characteristic droplet size to the orifice diameter is discussed. It is estimated that altogether 128 kg of NaK-78 (8 kg per RORSAT) was released on orbit. Simulation runs show that there are still 45,000 droplets with a total mass of 97 kg in orbit at the reference epoch 1 May 2005, whereas the smallest droplet has a diameter of 5 mm. Results of orbit propagation simulation runs are presented in terms of spatial density.     

低温氢气排放过程数值模拟

以低温氢气安全排放为目的,采用数值模拟方法对低温氢气直接排放和燃烧排放的流场进行分析.流场仿真计算采用了标准双方程k-ε湍流模型和氢氧单步燃烧模型.研究参数包括氢排放压力、流量、温度和环境风速,评价指标为氢扩散范围和燃烧范围.计算结果表明：燃烧排放燃烧范围小于直接排放氢扩散范围;排放压力增加、流量增大和温度降低均会使氢扩散范围和燃烧范围变大.

Integration and calibration of a multi slit spectropolarimeter

Multi-slit spectropolarimeter is a next-generation spectropolarimeter to obtain vector magnetic field information at high spatial, spectral, and temporal resolution for studying the magnetic structures on the Sun. Once developed, it can be used as ground based instrument at solar observatories, also as a space payload for various solar missions. A high spectral resolution is invariably an important parameter for accurate vector magnetic field measurements and faster cadence is required for the study of dynamical evolution of structures (e.g., solar flares, sunspots etc.) on the Sun and hence better understanding on the physics behind their evolution.
