Fully Nonlinear Ship-Wave Computations Using a Multipole Accelerated, Desingularized Method
(University of Michigan, 1997-04-01)
Chairperson: Robert F. Beck&&The inviscid ship-Wave problem with fully nonlinear boundary conditions is solved using a multipole accelerated, Desingularized Euler-Lagrange Time_domain Approach or DELTA method. The ...
Compendium of Ship Motion Calculations Using Linear Time-Domain Analysis
(University of Michigan, 1988-07-01)
Over the past four years a three-dimensional time-domain seakeeping computer code has been developed at The University of Michigan. The code uses linear system theory to determine the hydrodynamic forces acting on a vessel ...
Maritime Prospects in Northwestern South America
(University of Michigan, 1972-07-01)
This report summarizes a study of the maritime details of the northern Pacific coast of South America. The ports and national fleets of Colombia, Ecuador, and Peru are tabulated to summarize the data relevant to preliminary ...
Second Order Statistics and Discrete-Time Detection Modeling for Partially Saturated Processes
(Acoustical Society of America, 1985-03)
The basic problem in underwater detection is formulated under the general assumptions of partially saturated propagation of narrow‐band and acoustic signals. Expressions for the joint probability density function (PDF) of ...
Redesign of marine structures by perturbation
(Elsevier, 1988)
Finite element (FE) methods are extensively used for analysis of static and dynamic behavior of marine structures. Often predicted response is unacceptable from the point of view of design or operation. Improvement of ...
Invariant and consistent redundancy by large admissible perturbations
(Elsevier, 1992)
Structural perturbation theory has been developed over the past 16 years to relate two structural states modeled by the same Finite Element (FE) model but described by different values of the design variables. Relating an ...
Full scale wake and boundary layer instrumentation feasibility study
(Elsevier, 1980)
Fluid-flow measuring devices intended for full scale use were designed and tested. One device consisted of a rake supporting different types of pitot tubes. This will be used to obtain a velocity profile of the boundary ...
Forward Speed Effects on the Sway, Roll, and Yaw Motion Coefficients
(University of Michigan, 1978-11-01)
The added mass and damping coefficients for sway, roll and yaw are formulated for a ship with forward speed. The theory is similar to that given by Ogilvie and Tuck (1969) for the heave and pitch coefficients of a slender ...
