Moises is a senior studying Mechanical Engineering at George Mason University. He is currently working on doing high speed planing hull simulations to represent the Generic Prismatic Planing Hull (GPPH). After graduation, he plans on going to grad school to pursue a PhD in Aerospace Engineering. Outside of academia you can find him reading fiction novels, playing super smash bros, and working out.
As we get ready to kick off the 2019-2020 academic year, I’m thrilled to be settling into new lab space at GMU’s Potomac Science Center. While furniture is still on order, computing power has arrived along with enough SeaPerch and SeaGlide kits to last us through some kickoff STEM outreach activities. If you’re in the neighborhood, come by and visit: 1203 Potomac Science Center, 650 Mason Ferry Ave, Woodbridge VA!

STEM-on-Wheels is an ongoing project to outfit a mobile STEM trailer with fun, hands-on, science, technology, engineering, and mathematics activities for schools, after-school clubs, scouts, and other community groups. The new trailer made its first public appearance at the 2014 ASNE Fleet Maintenance and Modernization Symposium in Virginia Beach.

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).

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!
