1ST MARINE COMPUTATIONAL FLUID DYNAMICS SYMPOSIUM CALL FOR PAPERS The Navy's Hydroacoustics/Hydrodynamics Technology Center (H/HTC) is sponsoring the 1st Marine Computational Fluid Dynamics Symposium. This Symposium will provide a forum for the exchange of information among government activities, private industry, and academia on current work and new developments in Navy/marine related CFD as it applies to surface ships and submarines. The focus will be on applications and the role of the H/HTC in the community. The Symposium will be held at the Booz Allen Conference Center in McLean, VA, May 19-21, 1998. Papers/presentations on all aspects of CFD which relate to Navy/marine applications are solicited. Suggested topics include (but are not limited to): Direct Numerical Simulation Methods Reynolds-Averaged Navier-Stokes Methods Novel Applications Of CFD Ship dynamics and wave loads Vorticity-based methods Code Validation/Qualification Production Applications Complete Vehicle Flows Incompressible Flows Turbulence Modeling Free Surface Flows Grid Generation Visualization Ship air wakes Maneuvering Hydroacoustics Ship air wakes Stratified flows Propulsor Flows Flow Visualization Parallel Computing User Support Systems CAD Use/Application Vortex Dominated Flows Surface Geometry Definition Transient/Unsteady Flows High Reynolds Number Flows Large Eddy Simulation Methods Cavitation and multiphase flows Numerical/Computational Methods Experimental Results For Code Validation Special sessions are planned on Use Of CFD In The Marine Design Process, Advances In CFD Tools And Techniques, CFD Tool Transition From Research To Production, Role Of The H/HTC, Conveying CFD Info/Requirements/Desires To Experimentalists, Naval Experiments For CFD Code Validation, Grid Generation, Surface Geometry, and CAD Links, and State-Of-The-Art In Scaling Laws. ABSTRACT DEADLINE: FEBRUARY 20, 1998 Presentations will be accepted on the basis of their abstracts which must be submitted by February 20, 1998. Authors will be notified of acceptanceby February 27, 1998. Full papers are due July 31, 1998. Papers will be published electronically and distributed via CD-ROM on August 31, 1998.

This increasing role has been driven in part by fundamental Navy interests (e.g., reducing design and system costs, reducing design cycle time, enhancing system/platform performance, and rapid evaluation of novel/unique configurations) as well as the growing maturity of CFDtechnology. Although there is a great deal of overlap between the aerospace CFD community and the Navy/marine CFD community (e.g., turbulence modeling, numerical methods, grid generation, and computational requirements), there are also significant differences (e.g., predominately incompressible vs predominately compressible, extremely high Reynolds number flows vs moderate to high Reynolds number flows, confined flows, and free surface flows). In light of the increasing role CFD is playing in Navy/marine applications and the differences between the Aerospace and the Navy/marine communities, a new CFD Symposium is being established. For further information contact the Symposium Technical Chair, Dr. Donald W. Davis, Electric Boat Corporation, (860) 433-0861, ddavis@gdeb.com, or the Symposium Manager, Mr. Joel Leifer, SAVIAC/Booz Allen & Hamilton, (703) 412-7774, leifer_joel@bah.com. For current information visit the SAVIAC web page at http://saviac.xservices.com. PRESENTATION DETAILS Two categories of presentations will be accepted: full papers suitable for publication in the Symposium Proceedings; and short discussion topics consisting of viewgraphs with no written paper. Full papers will have a 25 minute technical presentation time plus 5 minutes for questions while short discussion topics will have a 15 minute presentation time with no question period. Presentations on both completed work and work in progress are encouraged. Separate sessions will be held for presentation of classified or limited distribution material. The full paper presentations must meet the following criteria: They must be previously unpublished, must be appropriate to Navy/marine community interests, and must not be overtly commercial. Standards for short discussion topics are similar except that they may include previously presented or published material. EXHIBITORS A limited number of spaces for technical/product displays will be available at the Symposium in the form of 8x10 tabletops. For more information please contact Sue Damanda at (703) 412-7712, fax: (703) 412-7500, email: damandas@bah.com, or fill out the "Exhibit Request" form available at http://saviac.xservices.com (available after 12/5/97).
