Vortex created by the passage of an aircraft wing, revealed by colored smoke Von Karman vortex street behind a drinking straw. Milk was poured into the water to make the current visible. A Kármán vortex street is demonstrated in this photo, as winds from the west blow onto clouds that have formed over the mountains in the desert. This ...
Two-dimensional slice through 3D Perlin noise at z = 0. Perlin noise is a type of gradient noise developed by Ken Perlin in 1983. It has many uses, including but not limited to: procedurally generating terrain, applying pseudo-random changes to a variable, and assisting in the creation of image textures.
Visible vortex rings can also be formed by the firing of certain artillery, in mushroom clouds, in microbursts, [1] [2] and rarely in volcanic eruptions. [3] A vortex ring usually tends to move in a direction that is perpendicular to the plane of the ring and such that the inner edge of the ring moves faster forward than the outer edge.
the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles
It is used for photorealistic effects of participating media like fire, explosions, smoke, clouds, fog or soft shadows. Like in the path tracing method, a ray is followed backwards, beginning from the eye, until reaching the light source. In volumetric path tracing, scattering events can occur along with ray tracing.
Smoke billows from a fire at the BioLab facility on Sunday in Conyers, Georgia. Atlanta residents were told to shelter inside as a smoke cloud containing chlorine covers city in haze on Thursday ...

During advection, a fluid transports some conserved quantity or material via bulk motion. The fluid's motion is described mathematically as a vector field, and the transported material is described by a scalar field showing its distribution over space. Advection requires currents in the fluid, and so cannot happen in rigid solids.
