Update: Stephanie Sherman’s work on air traffic management has won her a Virginia Space Grant Consortium graduate student research grant and an Airport Cooperative Research Program Graduate Research Award! Stephanie is working to develop a computational model of air traffic based upon a smoothed particle hydrodynamics-esque definition of aircraft interactions (like particle interactions in SPH). Through this approach, her tool will be able to model stochastic aircraft characteristics in addition to deterministic characteristics. Fundamentally, she is trying to provide a tool which can help address two important and challenging problems:
- Model aircraft interactions in a decentralized control scheme versus the current centralized control approach (e.g. the bulk of aircraft interactions being governed by instructions from air traffic controllers).
- Model manned and unmanned aircraft interact with non-deterministic factors (e.g. pilot skill, aircraft handling, etc…)
Both of these topics are of interest for study as part of the Next Generation Air Transportation System (NextGen).
To learn more about her excellent work, follow the tag for S_Sherman.

Graduate student researcher John Gilbert has received a prestigious NREIP Summer Internship position with the Naval Surface Warfare Center, Carderock’s Combatant Craft Division. Go John!
Folks often inquire about the accuracy of using an iPhone’s sensors as a data acquisition system. John Zseleczky from the U.S. Naval Academy Hydromechanics Laboratory recently conducted a very nice comparative study resulting in the attached data and has given me the go-ahead to share this publicly. Thank you very much John Z. and the USNA!
The underwater combustion of a propane-air mixture in an acrylic cylinder is captured on the video linked here from multiple angles. This experiment, led by Van Jones with assistance from Kariann Vander Pol and John Gilbert, is designed to provide visual data and pressure time-histories for future CFD validation studies. We have submitted this to the APS Division of Fluid Dynamics gallery of fluid motion competition this year! More information, including an extended abstract and higher resolution version of the video can be found at: http://arxiv.org/abs/1310.3523.
I am often asked if SCraMP can be useful on big ships as well as the small craft, for which it is named. My answer is always a resounding yes! There is nothing in the code that would confine it to small craft, and indeed, I have tried to make it as customizable as possible to suit a range of needs. With that in mind, the latest SCraMP release, hitting the app store today (https://itunes.apple.com/us/app/scramp/id456343416), adds two new safety metrics, one to help identify possible parametric roll conditions and one to provide guidance as to whether or not conditions might be making passengers sensitive to motion sickness. As always, if you have suggestions for app improvements or feedback on SCraMP v3.13, I am eager to hear from SCraMPers.
SCraMP users, a bug has been identified with the use of the safety metrics screen of SCraMP when running iOS7. I have submitted to Apple an update to solve the problem and hope to have the new iOS7 version of SCraMP released to you next week. Apologies for any inconvenience in the meantime.
Just got this e-mail from former post-doc Pankaj Kumar: “I am happy to inform you that I have been awarded best group project in IHPC/ASTAR. This award is for developing Lattice Boltzmann Method (LBM) solver within the OpenFOAM framework. My job in this project was to develop finite difference- and finite volume- based LBM solvers in OpenFOAM.” Congratulations Pankaj!
David Hickerson successfully defended his MS in July of 2013. In his research he used computational fluid dynamics simulations to study a sailboat heaving-to in a storm. His complete thesis is available online here.
This has been a great few months for SCraMP coverage. SCraMP was mentioned in the National Fisherman Best of 2012 article in January and received equally flattering coverage in the March/April Ship and Boat International. Thank you to those authors helping get the word out, and to those friends who are letting me know when they’ve seen SCraMP articles appear (both of these were pleasant surprises for me)!
Check out David Allen discussing Europa exploration online here.
A few weeks ago I had the tremendous honor of receiving this award. Below are my remarks and a wonderful picture of my advisor Armin Troesch who presented the award, ASNE president Ronald Kiss, and me (photo provided by ASNE–thanks Jared!).
Thank you. I am going to keep this short as my toddler in attendance will likely express out loud what many might be feeling regarding long acceptance remarks. Mostly I want to say a handful of thank you’s. I have been lucky to have really great advising, as an undergraduate from the late Pat Curtiss and as a graduate student from Armin Troesch. Thank you Armin for being such a wonderful advisor and setting my career on the right path. I am also fortunate to have fantastic colleagues at Virginia Tech, particularly Al Brown who has diligently kept me out of trouble, and my amazing students who make me look good. I would like to express my sincere gratitude to those program officers who have supported my work: Pat Purtell, Kelly Cooper, Bob Brizzolara, Eduardo Misawa, and Jay Falker. Every one of them took a chance on me being able to broaden my early research in ways that would support the ONR, NSF, and NASA missions, and I appreciate their faith in me, and my team’s abilities. I want to thank all the good folks at Carderock who have let me spend two summers in Bethesda working with Bill Belknap, Judah Milgram, Brad Campbell, and others, and a sabbatical at CCD enabled by Tim Coats, Dave Pogorzelski, and my personal favorite CCD researcher, my husband Charlie Weil. And I want to thank ASNE. ASNE has provided me leadership opportunities from the start of my career; opportunities to directly support or even work side by side with Captains, Admirals, Program Officers, SESs, industry leaders, and full Professors. ASNE leadership and staff have worked hard to make opportunities for students and young professionals. At this ASNE Day we have seen an exciting student program, put together by a team of young professionals led by Justin Stepanchick, showcasing exceptional student research. Wednesday night, the first ever Student Opportunities Committee, with direct representation to ASNE Council, was elected. ASNE is a warm place for students and young professionals and that, above all else, is why I am so honored to be receiving this Rosenblatt award for young naval engineers from ASNE. Thank you.
What do Europa geeks do for spring break? Go to JPL of course! Shown here is the VT EUROPA team: Craig Woolsey, David Allen, Matt Jones, and me pictured outside the Space Flight Operations Facility with our gracious host, Ray Crum.
