Preface

The Mechanical Engineering Congress 2020 Japan (MECJ-20) was held from 13th to 16th, September, 2020. This congress is scheduled to be held in Nagoya University at first, but changed to online because of the present social situation related to COVID-19. The conference has the keynote lectures from Prof. Takeo Kajishima of Osaka University and Prof. Ken-ichi Funazaki of Iwate University, 2 workshops and several organized sessions related to the fluid engineering division.

The issue of this Newsletter is “The Mechanical Engineering Congress 2020 Japan (MECJ-20)”, and 4 precious articles related to fluid engineering research and the operation of the online conference are reported. The research articles are contributed by 2 speakers of the keynote lecture and 2 student speakers nominated by the session organizer. All articles reflect the fact that many researchers, including students, continue their active research works, although COVID-19 restricts our activities severely. We expect that these articles are informative for engineers and researchers, and help to share the activities of the fluids engineering division in the future.

Finally, we hope COVID-19 subsides and we are looking forward to seeing again in next congress that will be held in Chiba University. We would like to thank all the authors for their contributions.
