The Mechanical Engineering Department is pleased to announce a SEMINAR on February 15, 2013 from 2-3pm in the Textile Building, Room 101E Conference Room.

SPEAKER: Dr. GEOFF COWLES of the Department of Fisheries Oceanography, School for Marine Science and Technology (SMAST)

TOPIC: An Efficient Method for Computing Steady and Time-Resolved Free Surface Ship Flows with Applications to Yacht Design.

ABSTRACT:
An efficient method for the computation of steady and time-dependent viscous fluid flow about advancing ships is presented. The baseline algorithm couples Chorin’s method of artificial compressibility with a finite-volume discretization of the Reynolds-averaged Navier-Stokes equations. A nonlinear multigrid scheme with residual smoothing and local time-stepping is used to accelerate convergence. The talk will provide background on the fundamental problem of ship resistance and provide details of the present numerical scheme used to resolve the necessary flow components. Comparison of computed results with experiment will be presented including datasets for the Series 60 {Cb=.6} hullform in steady flow and a Wigley hull in regular headwaves. Employment of the solver in the context of the design process for an IACC America’s Cup yacht will be discussed.

ALL ARE WELCOME, AND FIRST YEAR MS (GRAD) STUDENTS ARE REQUIRED TO ATTEND (all other MNE students are encouraged to attend).
