What (who) is boundary conditions - definition
Boundary conditions in fluid dynamics
Boundary conditions in fluid dynamics are the set of constraints to boundary value problems in computational fluid dynamics. These boundary conditions include inlet boundary conditions, outlet boundary conditions, wall boundary conditions, constant pressure boundary conditions, axisymmetric boundary conditions, symmetric boundary conditions, and periodic or cyclic boundary conditions.
Robin boundary condition
CLASS OF PROBLEMS IN PDES
Impedance boundary condition; Impedance Boundary Condition; Robin boundary conditions; Third type boundary condition; Impedance boundary conditions; Insulating boundary condition
In mathematics, the Robin boundary condition (; properly ), or third type boundary condition, is a type of boundary condition, named after Victor Gustave Robin (1855–1897).Gustafson, K.
Mixed boundary condition
MATHEMATICAL PROBLEM
Mixed boundary conditions
In mathematics, a mixed boundary condition for a partial differential equation defines a boundary value problem in which the solution of the given equation is required to satisfy different boundary conditions on disjoint parts of the boundary of the domain where the condition is stated. Precisely, in a mixed boundary value problem, the solution is required to satisfy a Dirichlet or a Neumann boundary condition in a mutually exclusive way on disjoint parts of the boundary.
Examples of use of boundary conditions
1. The new edition is quite literally ‘briefer‘. Gone are the purely technical concepts Hawking introduced, such as the mathematics of chaotic boundary conditions, while whole chapters are given over to more popular scientific ideas, such as relativity and quantum theory.
2. "As with all client–consultant relationships, boundary conditions were established within which to conduct the analysis ... Friends of the Earth, in conjunction with a consortium of NGOs and with increasing cross–party support from MPs, have been lobbying hard for the introduction of a ‘climate change bill‘ ... [The bill] is founded essentially on a correlation of 2C with 450 parts per million of CO2." In other words, Friends of the Earth had already set the target before it asked its researchers to find out what the target should be.
