Hydrodynamic Response to Partially Spanning Logjams
2022<p>Wood is a key part of a river ecosystem and affects both flow conditions and channel morphology. Wood accumulations or logjams may generate important habitat by increasing the upstream water surface elevation (backwater rise) and creating a downstream region with reduced flow velocity.

Hydrodynamic response of a pneumatic floating platform
Ocean Engineering, 2000This paper describes a numerical approach to model the dynamic response of a pneumatic floating platform, and the laboratory experiments and parametric study to verify the numerical results. The pneumatic platform is composed of an array of open-bottom vertical cylinders trapping pressurized air that displaces the water.

Hydrodynamic Responses Analysis for Tension Leg
Advanced Materials Research, 2013It is very important to do hydrodynamic analysis for TLP in its basic design process. This thesis studied the hydrodynamic behavior of a traditional TLP. DNV/SESAM software was used to do the modeling and calculating work. Totally three models were built, including panel model, mass model and structure model.

Response of aggregate structures to hydrodynamic stress
AIChE Journal, 1991Experimental procedures have been developed for investigation of floc breakage occuring in response to the hydrodynamic stress. Aggregates initially restrained by a stainless steel mesh were exposed to downward-directed flow, and the subsequent events including deformation and breakage severity were observed.

Hydrodynamic Response Characteristics of Barge with Mooring in Deep Ocean
Proceedings of the 2020 4th International Conference on Electronic Information Technology and Computer Engineering, 2020The finite element software based on the three-dimensional potential theory and Morison equation is used to simulate the mooring barge. The maximum amplitude of 6-DOF motion response of the barge in 5 wave directions is obtained by hydrostatic calculation in frequency domain, and the pressure distribution on the wet surface of the barge when ...

Hydrodynamic Response of Perforated Members
2017This chapter deals with hydrodynamic response of perforated cylinders under regular waves through computational fluid dynamics (CFD). The chapter deals with a brief introduction of fluid–structure interaction and wave–structure interaction. Variations in water particle kinematics along the depth when encountered by perforated members are discussed in ...

Physiological responses of CHO cells to repetitive hydrodynamic stress
Biotechnology and Bioengineering, 2009AbstractA majority of the previous investigations on the hydrodynamic sensitivity of mammalian cells have focused on lethal effects as determined by cell death or lysis. In this study, we investigated the effect of hydrodynamic stress on CHO cells in a fed‐batch process using a previously reported system which subjects cells to repetitive, high levels ...

Hydrodynamic response of inhomogeneous metallic systems
Il Nuovo Cimento B Series 11, 1974The response of an inhomogeneous metallic system is treated within the hydrodynamical theory in which the constitutive equation is obtained via a quasi-static extension of the theory of inhomogeneous electron gas. Formal expression for the frequency-dependent dielectric function of a metallic surface is derived and applications to other systems such as

Effects of Drafting on Hydrodynamic and Metabolic Responses in Front Crawl Swimming
Medicine & Science in Sports & Exercise, 2009Effects of drafting on the hydrodynamic and metabolic responses of the drafter behind and at the side of a passive and an active lead swimmer were related to the influence of a lead swimmer on the flow field of the draftee.Passive drag of the draft swimmer was compared for the nondrafting condition, in the drafting conditions behind a passive and an ...
