Biofouling is the accumulation of microbes, alage, plates, and biofilms on materials submerged in water. This can create a problematic drag on ships. Think about that the next time you are hanging out watching the tall ships in the Baltimore harbor!

Please join us Friday Feb 23rd at 7pm for as we are happy to welcome Dr. Abel Vargas to speak about his research:

Using Super Computers to Model the Impact of Biofouling on a Ship’s Performance

The talk: Roughness is seen in the marine industry either through corrosion, deterioration of paint, marine growth or a combination of all three. On ship hulls, roughness occurring through paint deterioration or biofouling can impact the ships performance by increasing its frictional drag. This increase in frictional drag adds an additional burden to the total ownership of a ship. The objective of the presentation is to present an improved modeling approach for quantifying the impact of biofouling of underwater hulls. Our team is using super computers to compute the drag penalty associated with biofouling that will help developed cleaning strategies.

Our awesome speaker: Abel Vargas is a Computational Scientist at Naval Surface Warfare Center Carderock Division. His research interests include Reynolds Averaged Navier-Stokes (RANS) modeling applied to submarines, surface ships, and other naval applications, as well as for design purposes. Currently his research focuses on the impact of hydrodynamic roughness due to biofouling on the resistance of surface ships. Vargas received a Doctor of Science degree in Mechanical and Aerospace Engineering from The George Washington University. Contact him at
