| Research Abstract |
Swirling flow behavior between two parallel disk shape plates was experimentally investigated with the aid of a particle image velocimetry (PIV). The experiment was performed at low Reynolds numbers (Re<100) to simulate the practical operation in a disk shape planar-type solid oxide fuel cell (SOFC). In the channel installed involute-type current collectors, a swirling flow was generated and its velocity was kept at nearly constant value toward the channel exit. This trend was observed regardless of flow rates, and hence flow uniformity was achieved over the wide range of Reynolds numbers. This improvement of flow field suggests that a control of thermal stress of the channel could be achieved by installing a circle involute flow passage.
