Editorial: Introducing Physical Review Fluids

Welcome to the first issue of Physical Review Fluids (PRFluids), the newest journal
published by the American Physical Society (APS). The field of fluid mechanics is
vibrant, international, and dynamic, with many interdisciplinary applications across
all areas of the physical and biological sciences, as well as engineering. PRFluids
aims to serve these diverse communities by publishing the very highest quality
research in all aspects of fluid mechanics. We are delighted with the very strong
response PRFluids has received, as evidenced by the high quality of the papers
published in this first issue, which are authored by intellectual leaders in the field.

John Kim and Gary Leal, founding Editors of PRFluids, are joined by an outstanding
team of Associate Editors and Editorial Board members, each of whom are
accomplished leading researchers in their fields. PRFluids is the latest addition
to the renowned Physical Review (Phys. Rev.) family of journals, and it is created
with the same commitment to excellence, timeliness, and service. We look forward
to engaging a broad readership that extends beyond the usual fluid mechanics
community.

PRFluids will publish papers both in the classical areas of fluid mechanics, and
also in the newer areas of the subject, such as flow problems involving complex
fluids, bio-fluid mechanics, and micro- and nano-fluid dynamics. The scope of the
journal will be reviewed regularly to ensure that it continues to serve the needs of
the community and captures the most interesting papers in the field.

...

The launch of PRFluids marks an exciting new initiative in fluid mechanics
publishing, and we are confident that it will quickly establish itself as the premier
journal in the field. However, the ultimate success of PRFluids depends upon the
quality of the submissions we receive. We call on all fluid mechanics researchers
to submit their best work to this journal and encourage their colleagues to do the
same. We look forward to receiving your contributions.

It looks like the first issue will be available online without cost to the reader through the end of 2016.

Here is the abstract of a paper on the formation of vortex rings:

This study investigated the relationship between the pinch-off of axisymmetric vortex
rings and the evolution of pressure in the shear layer being entrained into the vortex
rings. A piston-cylinder apparatus was used to generate the vortex rings, and five cases
of constant piston acceleration over distances ranging from zero (impulsive start) to eight
piston diameters were investigated. It was determined that increasing the distance over
which the piston accelerated increased the dimensionless formation time at which the
vortex ring pinches off, consistent with previous observations. A limiting value of vortex
ring formation number of approximately seven is approached when the piston is accelerated
over more than six piston diameters. For each case, the evolution of pressure in the shear
layer was calculated based on PIV measurements of the velocity field and spatial integration
of the corresponding pressure gradients using a recently developed algorithm. Plots of the
shear layer pressure in X-T diagrams aided in identifying key features of the pressure
associated with the evolution of vortex rings, including a high-pressure region that forms
behind the leading ring. By extrapolating the motion of this high-pressure region back to
the nozzle exit plane in the X-T diagram, its time of first appearance can be estimated. It is
found that the appearance of the extrapolated local pressure maximum in the shear layer at
the nozzle exit plane coincides with vortex ring pinch-off, as conventionally quantified by
the vortex ring formation number.

Fluid mechanics is an interesting topic.

Does anyone know any good comprehensive texts for the field - ones that may be trying to update/replace Batchelor's book on the subject?


That is post number 3003: it seems like now is a good time for a break until after the election or so...à bientôt!
