Micromechanical modeling of internal erosion [PDF]

European Journal of Environmental and Civil Engineering, 2011
Suffusion is the internal erosion process by which finer soil particles are detached from the solid matrix, and transported through constrictions by seepage flow. At the macroscopic scale, this is a bulk erosion process and corresponds to a source term in the mass balance equations.

Centrifuge Modelling of an Internal Erosion Mechanism [PDF]

Scour and Erosion, 2010
Suffusion is an internal erosion mechanism, which means the transport of fine particles within the soil due to hydraulic interflows. With the objective to characterize this mechanism and to study a scale effect presented in literature, a specific centrifuge bench is designed. Test specimens of mixture of sand and kaolinite are compacted in rigid walled

A Review of the Erosion of Thermal Barrier Coatings. [PDF]

, 2007
The application of thermal barrier coatings (TBCs) to components with internal cooling in the hot gas stream of gas turbine engines has facilitated a steep increase in the turbine entry temperature and the associated increase in performance and ...

Reservoir theory for studying the geochemical evolution of soils [PDF]

, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

Unsteady cfd analysis of erosion mechanism in the coolant channels of a rotating gas turbine blade [PDF]

, 2015
The two-phase flow in a rotating wedge mimicking the final portion of a blade turbine internal cooling channel is here presented and discussed focusing on unsteady motion and erosion mechanisms.

Monte Carlo modeling of low-energy electron-induced secondary electron emission yields in micro-architected boron nitride surfaces [PDF]

, 2019
Surface erosion and secondary electron emission (SEE) have been identified as the most critical life-limiting factors in channel walls of Hall-effect thrusters for space propulsion.

Microstructural analysis of sands with varying degrees of internal stability [PDF]

, 2014
Internal erosion involves the migration of particles through a geotechnical structure. Internal erosion poses a significant hazard to embankment dams and flood embankments.

Internal Erosion

, 2018
Chapter 9 ; International audience ; Internal erosion is one of the main causes of instabilities within hydraulic earth structures such as dams, dikes or levees. The mechanisms of internal erosion are deeply complex entailing many parameters, a number of which are coupled.

Experimental Study of the Premonitory Factors for Internal Erosion and Piping Failure of Landslide Dams [PDF]

, 2017
ydrodynamics is prerequisite for a better understanding of the complex mechanisms of internal erosion and piping failure of landslide dams. To this end, a series of large-scale (outdoor) physical experiments were conducted to evaluate the premonitory ...

Lateral Marsh Edge Erosion as a Source of Sediments for Vertical Marsh Accretion [PDF]

, 2018
With sea level rise accelerating and sediment inputs to the coast declining worldwide, there is concern that tidal wetlands will drown. To better understand this concern, sources of sediment contributing to marsh elevation gain were computed for Plum ...
