Plume shapes can be influenced by flow in the ambient fluid (for example, if local wind blowing in the same direction as the plume results in a co-flowing jet). This usually causes a plume which has initially been 'buoyancy-dominated' to become 'momentum-dominated' (this transition is usually predicted by a dimensionless number called the ...
The temperature gradients in axial and radial directions makes the fluid flow away from the hot end and the walls of the tube, towards the center axis. The liquid forms a droplet with a small contact area with the tube walls, a thin film circulating liquid between the cooler droplet and the liquid at the hot end.
Pyroclastic flows sweep down the flanks of Mayon Volcano, Philippines, in 2018. A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) [1] is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s; 60 mph) but is capable of reaching speeds up to ...
Talus cones produced by mass moving, north shore of Isfjord, Svalbard, Norway Mass wasting at Palo Duro Canyon, West Texas (2002) A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.
A hyperconcentrated-flow lahar can leave even frail huts standing, while at the same time burying them in mud, [8] which can harden to near-concrete hardness. A lahar's viscosity decreases the longer it flows and can be further thinned by rain, producing a quicksand -like mixture that can remain fluidized for weeks and complicate search and rescue.
a thing from Asia e.g. "Oriental carpet". a person from anywhere in Asia, other than Western Asia or Russia. Considered pejorative when used to describe persons. Polite US speakers use Asian instead, even for people from China and Korea. ouster: a person who ousts [41] (legal) dispossession, ejection or eviction, particularly when wrongful [13 ...
Concentrating on a task, one aspect of flow. Flow in positive psychology, also known colloquially as being in the zone or locked in, is the mental state in which a person performing some activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity.
Bicycle traffic barrier used to slow down cyclists circumvented by a detour in the form of a desire path, thereby showing a literal path of least resistance. In physics, the "path of least resistance" is a heuristic from folk physics that can sometimes, in very simple situations, describe approximately what happens.
