In addition to the need to reduce the pressure loss, the flow passing through the catalytic substrate should be as uniform as possible, which provides a uniform thermal distribution and high catalytic-conversion efficiency. Recently, we have reported that a flow deflector placed inside a catalytic-converter diffuser part can drastically reduce the pressure loss and improve the velocity profile in comparison with the no-flow-deflector case (Hirata et al., 2006 & 2008).  In those reports, our concern is restricted only to steady flow. On the other hand, practical exhaust flows often include various pulsative components. So, we investigate the effects of flow pulsation upon the flow-deflector performances such as the pressure-loss reduction and the velocity-profile improvement. As a result, the flow deflector can reduce the pressure loss and improve the velocity profile in comparison with the no-flow-deflector case, even on pulsating flow as well as steady flow.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2018.0000000099","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
