ディフューザ内の気流デフレクタによる圧力損失低減に関する実験と数値計算

Diffusers with high efficiency under both spatial and cost’s limitations are extensively desired in many industrial aspects. In our previous studies, we proposed a flow deflector introduced inside the diffuser-part of an automotive catalytic converter, in order to reduce energy loss and to improve thermal uniformity. In this study, we experimentally and numerically investigate the influence of the downstream substrate upon the performance of the flow deflector. As a result, it is revealed that the flow deflector is effective for diffusers as well as catalytic converters. By both experiment and computation, we have shown the flow inside the diffuser with the flow deflector.
