Что (кто) такое numerical instability - определение

FLUID BREAKUP OF A FALLING STREAM
Plateau-Raleigh instability; Rayleigh instability; Plateau-Rayleigh instability
  • PEG]] in water
  • Rain water flux from a canopy. Among the forces that govern drop formation: Plateau–Rayleigh instability, [[Surface tension]], [[Cohesion (chemistry)]], [[Van der Waals force]].
  • Intermediate stage of a jet breaking into drops. Radii of curvature in the axial direction are shown. Equation for the radius of the stream is <math>R(z) = R_0 + A_k \cos(kz)</math>, where <math>R_0</math> is the radius of the unperturbed stream, <math>A_k</math> is the amplitude of the perturbation, <math>\scriptstyle z</math> is distance along the axis of the stream, and <math>k</math> is the wave number
  • Water dropping from a tap

Genome instability         
HIGH FREQUENCY OF MUTATIONS WITHIN THE GENOME OF A CELLULAR LINEAGE
Genomic instability; Genetic instability
Genome instability (also genetic instability or genomic instability) refers to a high frequency of mutations within the genome of a cellular lineage. These mutations can include changes in nucleic acid sequences, chromosomal rearrangements or aneuploidy.

Plateau–Rayleigh instability

The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability and is part of a greater branch of fluid dynamics concerned with fluid thread breakup. This fluid instability is exploited in the design of a particular type of ink jet technology whereby a jet of liquid is perturbed into a steady stream of droplets.

The driving force of the Plateau–Rayleigh instability is that liquids, by virtue of their surface tensions, tend to minimize their surface area. A considerable amount of work has been done recently on the final pinching profile by attacking it with self-similar solutions.
