WebUsing this, the equation for the concentration field is ∂c ∂t +∇.(cu) = ∇.(D∇c) (4.16) If the diffusion coefficient is a constant, the equation for the concentration field becomes ∂c … Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this system, the sphere is taken as a unit sphere, so the radius is unity and can generally be ignored. This simplification can also be very useful when dealing with objects such as rotational matrices.
WebThe incompressible Navier–Stokes equations with conservative external field is the fundamental equation of hydraulics. The domain for these equations is commonly a 3 or less dimensional Euclidean space, for which an orthogonal coordinate reference frame is usually set to explicit the system of scalar partial differential equations to be solved. WebNewton's laws are easy to use in Cartesian coordinates, but Cartesian coordinates are not always convenient, and for other coordinate systems the equations of motion can become complicated. In a set of curvilinear coordinates ξ = ( ξ 1 , ξ 2 , ξ 3 ), the law in tensor index notation is the "Lagrangian form" [10] [11]
