Cylindrically symmetric
WebA. Cylindrically symmetric spacetimes It is interesting to note that, despite the extensive studies of cylindrical spacetimes in the past several decades, in the literature there still exist confusions in the de nition of cylindrically symmetric spacetimes and (wrong/false) claims. A reason for that is probably con- WebThe temperature field is cylindrically symmetric, ranging from infinite at r = 0 to T ∞ at the far field. In reality though, if T ∞ is less than the melting temperature T melt of the material, the high temperature developed around r = 0 would lead to melting of the material and a cylindrical interface would emerge separating the solid phase ...

WebA cylindrical symmetric solution of Einstein’s field equations possessing a naked curvature singularity on the symmetry axis was presented. The spacetime is conformally flat and static, and the matter-energy content anisotropic … WebAn analytical model of the thermal effects of cylindrically symmetric heating in laser rods is presented. We discuss two different methods for calculating the temperature distribution and thermal effects such as the thermally induced lens and thermal birefringence. One method is based on Taylor series; the other, on the integration of differential heating …
WebIn the case of an infinite uniform (in z) cylindrically symmetric mass distribution we can conclude (by using a cylindrical Gaussian surface) that the field strength at a distance r from the center is inward with a magnitude of 2 G / r times the total mass per unit length at a smaller distance (from the axis), regardless of any masses at a larger … WebCylindrically Symmetric Charge Densities Consider the volume charge densities ρ v (r) that are functions of cylindrical coordinate ρ only, e.g.: () 2 1 vvr or r e ρρρ ρ ==− We call …
