NICOP - Experimental and Viscous Flow CFD (Computational Fluid Dyramics) Study of Added Powering for Ships in Regular Waves
Abstract
Notes to TD: The total cost of this effort is about $600K with 50% cost share (~$300K) from the performing organization (Force Tech in Denmark). ONR HQ (Dr. Thomas Fu) and ONRG will cost share ~ $100K per year for 3 years. I will only be processing the grant application since I have been working with Force Tech on the proposal since 2015. Once the grant is awarded, this grant will be transferred to Dr. Sal Ahmed for monitoring. a. Technical: Focus of this effort will be on investigation and quantification of the added powering originating from waves for a displacement vessel using RANS (Reynolds Averaged Navier-Stokes) based viscous flow CFD (Computational Fluid Dynamics) and towing tank testing. Calculations of added powering will be carried out in regular head seas to investigate the possibility to use CFD for generation of reliable added powering data. In addition to generation of information about the motions and the added powering due to waves, the CFD results will also be used to study the flow field in order to learn about the physics of the complex flow. Scale effects of the results from different size ship model used in the experiments will be studied carefully. b. Relevance: This study will contribute to the fundamental understanding of ship performance in waves especially the detail effective wake inflow to propeller. It eventually will help the design of hull forms and propeller with better performance in waves. This effort is directly related to the U.S. Navy Platform Design and Survivability S&T focus area. The PI will work closely with the U.S. Partner, Frederick Stern of the University of Iowa (UI). The experimental data will be available to public as a benchmark validation case. c. Coordination: Dr. Thomas Fu (ONR Code 331), Dr. Sal Ahmed (ONRG) d. Desired outcomes: (1) a comprehensive experimental database for CFD validation (added resistance and added power power), (2) CFD simulation of ship performance in waves and with forward speed, and (3) archival level technical papers to enhance the understanding of ship performance in waves.
