Contoh plume

• Investigation of laser ablated plumes using fast photography.

• The growth of basal solid released plumes of compositionally depleted fluid from the floor.

• The transition is typically associated with intermittent bursts, which may involve spatially modulated oscillations and merging or splitting of individual plumes.

• At any instant the spatial pattern is irregular and video sequences show that individual plumes grow, decay and disappear aperiodically.

• Owing to the stratification these plumes expand rapidly as they impinge upon the upper boundary.

• They are again disposed on an irregular hexagonal lattice but the number of plumes is different and there is no reflection symmetry.

• Even on the vertical wall in figures 8(d) and 9(d), only a few plumes penetrate.

• In the corners themselves are plumes of the same sign as in the centre.

• He extends this effort here with a new text specifically dedicated to a description of mantle plumes, their causes, and their effects on surface geology.

• Using real water or air-borne plumes, or real antennae sensors, saves effort in modelling and makes validation more straightforward.

• There is no entrainment into these plumes, even a t zero surface tension.

• Next, alternate plumes develop an annular structure with a sinking core and then split apart to form imperfect tiny squares (with five plumes).

• Convection is strongly aperiodic but the plumes now tend to be disposed in patterns that are roughly hexagonal.

• The basic sequence, starting with steady convection in an irregular hexagonal pattern and proceeding via intermittent behaviour to chaotic large-scale plumes, is repeated.

• Almost symmetric patterns alternate aperiodically with episodes when plumes migrate and amalgamate, squeezing out their intermediate neighbours.
