Bui, Dat Duc (Texas A&M University. Libraries, 1993)The study of the inverse scattering problem for electromagnetic waves, especially under consideration of such realistic effects as spatial inhomogeniety, dispersion, dissipativity and multiple spatial dimensions, is based ...
-
Choi, Hae-Jin (Texas A&M University, 2007-04-25)A comprehensive experimental study was conducted to produce benchmark wave kinematics data for five different regular waves and the maxima of four different irregular wave trains. Two of the irregular waves generated are ...
-
Yu, Kai (2009-05-15)An interface-preserving level set method is incorporated into the Reynolds- Averaged Navier-Stokes (RANS) numerical method for the time-domain simulation of green water effects. This generalized method can be used to ...
-
Smith, Ernest Ray (Texas A&M University, 2006-10-30)Laboratory experiments were performed to study and improve longshore sediment transport rate predictions. Measured total longshore transport in the laboratory was approximately three times greater for plunging breakers ...
-
Martinez Farfan, Jose Alberto (2013-04-22)Previous work on modal analysis of mooring lines has been performed from different theoretical formulations. Most studies have focused on mooring lines of a single homogeneous material, and the effect of added mass and ...
-
Ardani, Samira (2016-05-18)In this dissertation, we evaluate the performance of nonlinear models, and the effects of bound waves in nearshore wave models are studied mathematically and numerically. The first part of this study concerns the evaluation ...
-
Nie, Chunyong (2011-08-08)For high speed vessels and offshore structures, wave impact, a main source of environmental loads, causes high local stresses and structural failure. However, the prediction of wave impact loads presents numerous challenges ...
-
Jiang, Boyang (2012-02-14)As the forecasting models become more sophisticated in their physics and possible depictions of the nearshore hydrodynamics, they also become increasingly sensitive to errors in the inputs. These input errors include: ...
-
Zhu, Liyun (2020-11-05)A nonlinear three-dimensional finite element numerical code, called RISER3D, has been developed to perform the static, eigenvalue, and dynamic analyses for slender structures such as beams and marine risers. Distinction ...
-
Tahvildari, Navid (2012-02-14)The nonlinear interactions between long surface waves and interfacial waves in a two-layer fluid are studied theoretically. The fluid is density-stratified and the thicknesses of the top and bottom layers are both assumed ...
-
Huang, Han (2013-07-27)Top Tensioned Riser (TTR) and Steel Catenary Riser (SCR) are often used in a floating oil/gas production system deployed in deep water for oil transport. This study focuses on the improvements to the existing numerical ...
-
Yang, Chan K. (2010-07-14)Nonlinear coupling problems between the multiple bodies or between the mooring/riser and the offshore platform are incorporated in the CHARM3D-MultiBody, a fully coupled time domain analysis program for multiple bodies ...
-
Tahchiev, Galin Valentinov (2009-05-15)Hurricanes Ivan, Katrina, and Rita tracked through a high-density corridor of the oil and gas infrastructures in the Gulf of Mexico. Extreme winds and large waves exceeding the 100-year design criteria of the MODUs during ...
-
Dong, Qian (2010-07-14)In the present study, a fifth-order weighted essentially non-oscillatory (WENO) scheme was built for solving the surface-capturing level-set equation. Combined with the level-set equation, the three-dimensional Reynolds ...
-
Min, Hyunseong (2018-04-27)Hywind, the world’s first operational Floating Offshore Wind Turbine (FOWT), is constrained by a delta mooring system to improve the yaw station-keeping capacity. In this study, a mooring line-simulation code in COUPLE-FAST ...
-
Hou, Tiancong (2014-08-13)Free Standing Hybrid Riser (FSHR) is an innovative concept for the riser to transport oil and gas from the seabed to a floating production platform deployed in deep water. A FSHR mainly consists of a buoyancy can, a vertical ...
-
Bae, Sang-Yun (2009-05-15)This study investigated Floating Production Storage and Offloading (FPSO) responses under wave and current interactions. A higher order boundary element method (HOBEM) was adopted to probe the behavior of an FPSO. Forces ...
-
Lee, Yongseok (2014-07-24)Moored buoy systems are often deployed by oceanographers to gather scientific information on local and global changes in the water column, weather patterns and climate change. The data they gather is first transmitted to ...
-
