Physics and Control of Cavitation MAR 2006 37 pages
Authors:  Jean-Pierre Franc; GRENOBLE UNIV (FRANCE)
The full text of this report is available for sale.The objective of the present chapter1 is to provide the basic concepts and tools required to understand the inception and development of cavitation in liquid flows. The influence of various parameters as the boundary layer and nuclei content is discussed. A special attention is given to thermal effects which may significantly influence the development of cavitation in thermosensitive fluids as cryogenic liquids. The main types of cavitation (partial attached cavities, ...

Prediction of Equiaxed Grain Density in Multicomponent Alloys, Stirred Electromagnetically 90
Authors:  P. Desnain; Y. Fautrelle; J. L. Meyer; J. P. Riquet; F. Durand; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.A phenomenological model, which numerically simulates nucleation and growth of equiaxed grains in a stirred melt, is presented; process parameters are stirring intensity and alloy composition; volume grain density and the maximum undercooling, together with intermediate parameters such as undercooling at the beginning of nucleation, nucleation rate, growth rate, ect., the effect of compositional changes is discussed; the influence of low level additions (for instance titanium), independently of the effect ...


Waves on Vortex Cores and Their Relation to Vortex Breakdown, JUL 1983
Authors:  T. Maxworthy; M. Mory; E. J. Hopfinger; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.It was conjectured by Hopfinger, Brown and and Gagne (1982), (1) that traveling, large amplitude 'kink' waves, observed by them in rotating, turbulent fluid might be at the origin of vortex breakdown and small scale turbulence production. This observation motivated us to study such waves experimentally on isolated vortices under controlled conditions. Their characteristics are interpreted in terms of theories based on the localised induction equation. It is found that ...


Incremental Stress-Strain Relationship for Cohesionless Soil JUN 1976
Authors:  F. Darve; S. Labanieh; R. Chambon; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.We propose an incremental stress-strain relationship valid for the non-viscous range of soils behavior. The theoretical results obtained from the integration of this relationship were compared systematically with the results of cubical triaxial tests. The parameters of this relationship are evaluated from the results of conventional compression and extension triaxial tests. This relationship covers the different aspects of stress-strain characteristics: variations of Young's modulus and Poisson's ratio with confining pressure, ...


Mechanical Behavior of Granular Material 1975
Authors:  Jean Biarez; Bernard Cambou; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.For compressibility tests the authors propose a law which can be used for range of high stresses, they show the existence of a threshold of stress at which a significant breakage of particles starts. Then the authors study the influence of particle size on mechanical behavior of granular materials (angle of internal friction, triaxial moduli, oedometer moduli, particle breakage). At last they study the influence of particle shape on the ...


An Application of Seismic Survey to Landslide Investigation 1972
Authors:  J. Biarez; C. Azimi; P. Desvarreux; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.The applications of seismic method for landslide investigation show that the latter must be considered as a rapid method with a large economical efficiency. One of its advantages is the possibility to follow continuously the seismic discontinuity surface and under certain favourable circumstances, the seismic data are sufficient to resolve the main problems in the landslide area, though in general the seismic data would be completed by the general geological ...


Parameters for Stability Analysis of a Dyke on Sensitive Clay 1972
Authors:  Jean Biarez; Bohumil Boucek; GRENOBLE UNIV (FRANCE)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.The constructions on the sensitive clays are to be built carefully, using the controlled loading technique to match the evolution of the shear strength and its low initial value. Two superposing processes are to be considered: (a) The increase of the effective stress during the consolidation increases the shear strength. If the permeability of the soil strata in the horizontal direction is much greater than in the vertical one, the ...
