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

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 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 ...

Hydrodynamic Effects in Earthquake Response of Embankment Dams
Journal of the Geotechnical Engineering Division, 1982Utilizing a recently developed analytical procedure, the significance of hydrodynamic effects in the earthquake response of embankment dams is evaluated. Effects of dam-fluid interaction, water compressibility and fluid-foundation interaction are all considered in this study.

Response of anammox metacommunity to varying hydrodynamic wash
Journal of Water Process Engineering, 2020Abstract The responses of microbial community structures and bacterial interactions of anammox process to hydrodynamic wash was investigated. Based on the operation of three identical anammox reactors with the same nitrogen loading rate, we found that though the three reactors achieved comparable nitrogen removal performance during the whole ...

Hydrodynamic Dispersive and Advective Processes in Watershed Responses
Journal of Hydrologic Engineering, 2004A model for estimating the watershed response is presented and used for assessing how the watershed size and spatial variability of the hydrodynamic parameters (i.e., wave celerity and dispersion coefficient) affect the comparative importance of advective processes with respect to hydrodynamic dispersive processes. A parameter Ω was defined to quantify

Hydrodynamic response of tension-leg platforms—A model
Experimental Mechanics, 1993The tension-leg platform (TLP) is a hybrid type of offshore platform, fixed for the vertical degrees of freedom and compliant for the horizontal degrees of freedom. The platform structure is connected to the sea-bed foundation by vertical moorings (tension legs) which are kept in tension under all conditions by the excess buoyancy over weight of the ...

Load-Responsive Hydrodynamic Bearing for Downhole Drilling Tools
Journal of Tribology, 2006A load-responsive hydrodynamic thrust bearing has been developed that has capabilities to operate under higher load and speed combinations than the current bearing designs used in roller cone drill bits, downhole drilling motors, and other downhole drilling tools.

Frequency response of electrochemical sensors to hydrodynamic fluctuations
Journal of Fluid Mechanics, 1990The response of mass transfer to a small mass sink to hydrodynamic fluctuations in the concentration boundary layer has been calculated as a function of frequency. The dimensionless local flux was expressed as a series expansion of the dimensionless local diffusion layer thickness η and the dimensionless local characteristic frequency ξ in the low ...
