To investigate the potential of utilizing visible spectral imaging for controlling the plasma boundary shape during stable operation of plasma in future tokamak, a D_α band symmetric visible light diagnostic system was designed and implemented on the Experimental Advanced Superconducting Tokamak(EAST). This system leverages two symmetric optics for joint plasma imaging. The optical system exhibits a spatial resolution less than 2 mm at the poloidal cross-section, distortion within the field of view below 10%, and relative illumination of 91%.The high-quality images obtained enable clear observation of both the plasma boundary position and the characteristics of components within the vacuum vessel. Following system calibration and coordinate transformation, the image coordinate boundary features are mapped to the tokamak coordinate system. Utilizing this system, the plasma boundary was reconstructed, and the resulting representation showed alignment with the EFIT(Equilibrium Fitting) results. This underscores the system's superior performance in boundary reconstruction applications and provides a diagnostic foundation for boundary shape control based on visible spectral imaging.

唐宋交替时期政治支配特征是全国化的方镇(节度使)军事支配体制。这种军事支配体制亦被位于中国周边的东亚诸种族所接受。方镇体制既是周边诸种族为了表示从属于中国而有的支配体制,又为周边诸种族从中国独立并建立国家起到支撑作用。具体过程分为以下三个类型进行讨论:(1)种族在独立国家的形成及其领域扩大的过程中,领有中原王朝的一部分,并吸收该地域的方镇体制(辽、金);(2)国家形成过程中或国家形成之后,将方镇体制导入到自己支配的地域内部(南诏、高丽);(3)由方镇体制发展为独立国家的形成(西夏、大越=安南)。

A cross-flow wind turbine near a structure was tested for the performance. The results showed that the performance of a cross-flow wind turbine near a structure was up to 30% higher than the one without a structure. In addition, we tried to get higher performance of a cross-flow wind turbine by using an Inlet Guide Structure and a Flow Deflector. An Inlet Guide Structure was placed on the edge of a structure and a Flow Deflector was set near a cross-flow wind turbine and can improve ambient wind environments of the wind turbine, the maximum power coefficients were about 15 to 40% higher and the tip speed ratio range showing the high power coefficient was wide and the positive gradients were steep apparently.

Effects of Aspect Ratio in a Transonic Shock Tube Airfoil Flow

Journal of Thermal Science 2012年第5期21卷 435-440页

作者： Masashi kASHITANI keita MIURA shinichiro NAkAO Yutaka YAMAGUCHI Department of Aerospace Engineering National Defense Academy1-10-20 Hashirimizu Yokosuka 239-8686 JAPAN Department of Mechanical Engineering Nagasaki Institute of Applied Science 536 Aba-MachiNagasaki 851-0193 JAPAN

In the present study, the flow visualizations were performed around the NACA 0012 models which differ in aspect ratios. We discussed the effects of the aspect ratio in the test models. Additionally the unsteady, two-dimensional, compressible Euler equations were solved for the NACA 0012 airfoil. Experiments were performed utilizing the conventional gas driven shock tube as the intermittent transonic wind tunnel. The aspect ratios of the models are about 0.86 and 1.5, respectively. The Mach numbers M 2 are about 0.84. The Reynolds numbers of the present experimental conditions were constant that Re based on chord length is about 4.0×10 5 . The results are as follows: in different aspect ratios, the difference of the shock wave location is confirmed though the Mach number and Reynolds number are same. It indicates the different correction Mach number by the effects of the side wall boundary layer though the nominal Mach number measured the same value. Also, on the difference of shock wave location for the effects of the aspect ratio, the tend of CFD shows the qualitative agreement with the result of an experiment.
