Research Interests

Active areas of research are in nonlinear water-wave dynamics, contact-line dynamics, drag-reduction technologies, and coastal engineering. Energy dissipation, vorticity dynamics in near-breaking and breaking waves are studied experimentally using PIV and other non-intrusive techniques. Drag-reduction technologies such as polymers are investigated. Wind effects on these mechanically generated waves are also studied. Contact-line dynamics in oscillatory flows are studied experimentally and numerically. Steep and breaking standing waves and their nonlinear dynamics have been investigated using Faraday waves. Long-wave and short-wave interactions are investigated as well as the viscous drift induced by short waves. Specifically, parasitic capillary waves generated by steep gravity waves are studied. High-speed video in conjunction with a laser sheet provides spatial information. In the experimental investigations, temporal and spatial data are used to yield both frequency and directional (wavenumber) spectra. Within coastal engineering, present interests are in the numerical modeling of shorelines and structures, and the quantification of longshore and cross-shore sediment transport. Specifically, these areas include such topics as the relationship between directional wave spectra and its attendant sediment transport; and, a description of the beach profile for non-monotonic cross-shores.

New Research Programs Planned

1-Hydroplastic blast panel research is in its initial stages. Provisional Patent received. Proposal preparation has begun for ONR (as DARPA recommended). Research with D.G. Karr, NAME.

2-Fluid dynamics of sloshing in LNG carriers. Discussions are underway with ExxonMobil regarding an investigation of this phenomenon. Research with W.W. Schultz, ME. Also, sloshing in enclosed ship containers to replace conventional locks. Talks with Dalian University, Dalian, China.

3-Nature-assisted erosion-accretion dredging program is an initiative by Perlin, Meadows, Choi, and Nwogu to obtain funding to investigate using gas or liquid injection to resuspend sediment to reduce dredging requirements in harbors, bays, estuaries, and ports, and to reduce the need for beach fills and hard structures on open coastlines. This effort has been proposed to the US Army Corps of Engineers who said it held promise; however, they had no funds to support it. I have sent it to NSF Fluid Dynamics and Hydraulics, Chemical & Transport Systems Div., and I received a positive response for submission to them and to the Physical Oceanography Div.
