HYDRODYNAMIC PROCESS [3 records]

Record 1 2019-06-12

English

Subject field(s)
  • Transport of Water (Water Supply)
DEF

... a pipeline conveying water by gravity from a source of supply in a stream or body of water to an intake well.

CONT

An important place within water supply systems is represented by the adduction pipes. The flow in adductions can be characterized by free level under the pressure, or in certain situations in a mixed manner. The modification of design parameters and of the hydrodynamic regime in the adductions for water is developed in a continuous destructive process or variable in time. The multiple actions determine the modification of the constructive and functional parameters of the adduction, diminish the mechanic resistances, disturb the stability and decrease the safety in the construction exploitation.

DEF

"heat sink": Tooling applied adjacent to weld zone to absorb heat and to prevent heat flow into parent material.

DEF

"heat sink": any objects, such as a solid mass of heat-conducting material, placed at work to prevent local overheating during an operation such as soldering.

DEF

"sink" : a body or substance used for the disposal of a fluid or heat in the course of a hydrodynamic or a thermodynamic process.

Record 3 1994-03-08

English

Subject field(s)
  • Mathematics
  • Computer Graphics
CONT

A related problem is viscous fingering, observed most conveniently at the interface of two liquids between two glass plates. For two miscible liquids, like gelatin and water, a DLA-like structure appears when one liquid invades the other.... This growth process is the result of a hydrodynamic instability between the liquids. As in DLA, any small "bump" on the interface will tend to grow predominantly at the tips because the pressure gradient, which drives the growth, is largest at the tips.

French

Domaine(s)
  • Mathématiques
  • Infographie
CONT

Forme de géométrie très irrégulière relevant d'une description fractale, présentant des protubérances digitiformes et qui illustre les phénomènes de percolation par invasion tels l'injection de pétrole dans un milieu poreux, le moulage métallique ou le stockage du gaz sous pression dans un sous-sol préalablement imbibé d'eau.
