Next-Generation Computational Methods in Ship Hydrodynamics

Program Period: 
1/1/16 - 12/31/17

Assemble an expert team to successfully compete for an upcoming ONR MURI call for research on understanding the intricacies of ship movement through water

An improved understanding of ship hydrodynamics, including the mechanics of air entrainment and bubble wake, is critical to the US Navy. For example, bubble wake is the main source of ship vulnerability since a vessel can easily be located via satellite from its wake alone. Bubble formation is a complex phenomenon and an example of nanoscale dynamics influencing macroscale behaviors. The Office of Naval Research has recognized that without the development and validation of next-generation predictive computational methods, the understanding of multiscale phenomena relevant to ship hydrodynamics will remain elusive. Current modeling and computation strategies can take up to six months to execute. Prof. Gibou’s research is geared towards strategies that can be done in a matter of hours for complex geometries. Prof. Luzzatto-Fegiz’s work in experimental and theoretical fluid dynamics will be leveraged to validate the computations.

The PIs plan to assemble a winning team by reaching out to several institutions working on ship hydrodynamics, organizing a workshop to articulate the technical challenges, and traveling to the Navy Research Lab to consult with scientists and program managers, all as part of preparatory activity for an ONR MURI call expected in 2017.
