Temperature advection
Webwhere c is the variable of interest (species concentration for mass transfer, temperature for heat transfer),; D is the diffusivity (also called diffusion coefficient), such as mass diffusivity for particle motion or thermal diffusivity for heat transport,; v is the velocity field that the quantity is moving with. It is a function of time and space. For example, in advection, c … The advection equation is the partial differential equation that governs the motion of a conserved scalar field as it is advected by a known velocity vector field. It is derived using the scalar field's conservation law, together with Gauss's theorem, and taking the infinitesimal limit. One easily visualized example of … See more In the field of physics, engineering, and earth sciences, advection is the transport of a substance or quantity by bulk motion of a fluid. The properties of that substance are carried with it. Generally the majority of the advected … See more The advection equation also applies if the quantity being advected is represented by a probability density function at each point, although accounting for diffusion is more difficult. See more • Atmosphere of Earth • Conservation equation • Courant–Friedrichs–Lewy condition See more The term advection often serves as a synonym for convection, and this correspondence of terms is used in the literature. More technically, convection applies to the … See more In meteorology and physical oceanography, advection often refers to the horizontal transport of some property of the atmosphere or ocean, such as heat, humidity or salinity, and convection generally refers to vertical transport (vertical advection). … See more
