The design secret of Kyokusui-no-En’s meandering channel 总被引:1,自引:0,他引:1
The purpose of this study is to investigate the characteristics of the flow through the Jonangu channel which is used for
ceremonial game called as ‘Kyokusui-no-En’ in Japanese. The geometry of the channel is measured, a visualization technique
is used to measure the actual flow characteristics, and then a numerical flow model is used to represent the flow including
unsteady flow characteristics. Numerical model of drifting cup is introduced to investigate an interaction between flow and
motion of the cup. Finally, the intention of the channel design is interpreted from the viewpoint of fluid mechanics using
observed and calculated results. 相似文献

We point out a possibility of strange giant resonances that can be excited by the (K ?,π?) reaction on nuclear targets. Recent experimental data on40Ca are analyzed from this point of view. 相似文献

The generation and recognition of a record-length 511-chip optical code is experimentally demonstrated by use of a superstructured fiber Bragg grating (SSFBG) with a chip rate of 640 Gchips/s. Very high reflectivity (92%) is achieved with high-quality correlation properties. The temperature deviation tolerance is approximately +/- 0.3 degrees C, which is within the package's temperature stability range (+/- 0.1 degrees C). Experimental results show good agreement with the theory. They indicate the SSFBG's potential for processing a long optical code with an ultrahigh chip rate, which could significantly improve the system's performance. 相似文献

By using a sodium atomic vapor we have observed a honeycomb-type multiple-diffraction pattern that was due to a grating induced optically by three noncollinear bichromatic excitation beams. In particular, when the two incident frequencies satisfy the two-photon resonance condition and the atomic density is high, the diffraction is enhanced by electromagnetically induced transparency, and strong Stokes and anti-Stokes components are generated in well-defined directions. 相似文献
