ディスク形MHD発電機内の放射状超音速流れの挙動 : 第1報,非発電時の計測と3次元数値解析

抄録

Structures of supersonic radial flow in a disk MHD channel have been investigated by experiments and numerical calculations. Total pressure profiles across the channel height and static pressure distributions along the radial direction on both surfaces of a disk MHD channel were measured in the absence of the MHD effect. Furthermore, three-dimensional time-dependent calculations by means of the MUSCL-type TVD scheme were carried out. Measurements and calculations have shown that the working gas flow becomes asymmetric in the height direction due to some pseudo shock waves, and a large region of flow separation exists downstream of the channel.
