本实验旨在提高激波管驱动的盘式CCMHD发电机的性能。为此，实验装置安排如下：（1）引入了进气涡流。(2)盘式发生器的面积比较小。(3)使用铯籽晶氦气作为工作介质。不仅这些因素，而且均匀的等离子体的产生有助于突出的性能，其特征在于在2250 K的停滞温度和0.14 MPa的停滞压力下的63%的等熵效率和30.8%的焓提取率。此外，获得了1.23 MW的最大电功率输出和297 MW/m3的最大功率密度。© 2006 Wiley Periodicals，Inc.

The present experiment has aimed at the improvement in the performance of a shock‐tube‐driven disk CCMHD generator. For that purpose, an experimental setup was arranged as follows: (1) An inlet swirl was introduced. (2) The area ratio of the disk generator was small. (3) A cesium‐seeded helium gas was used as a working medium. Not only these factors but also the production of a homogeneous plasma contributed to outstanding performance characterized by an isentropic efficiency of 63% and an enthalpy extraction ratio of 30.8% at a stagnation temperature of 2250 K and stagnation pressure of 0.14 MPa. Furthermore, a maximum electrical power output of 1.23 MW and a maximum power density of 297 MW/m3 were obtained. © 2006 Wiley Periodicals, Inc.
