It is named after the Indian astrophysicist Subrahmanyan Chandrasekhar. The number's main function is as a measure of the magnetic field, being proportional to the square of a characteristic magnetic field in a system. == Definition == The Chandrasekhar number is usually denoted by the letter $\backslash \; Q$, and is motivated by a dimensionless form of the Navier-Stokes equation in the presence of a magnetic force in the equations of magnetohydrodynamics: :: $\backslash frac\backslash left(\backslash frac\}\; \backslash cdot\; \backslash nabla)\; \backslash mathbf\backslash right)\backslash \; =\backslash \; -\; p\backslash \; +\backslash \; \backslash nabla^2\; \backslash mathbf\backslash \; +\backslash frac\; \backslash \; (\; \backslash wedge\; \backslash mathbf)\; \backslash wedge\backslash mathbf,$ where $\backslash \; \backslash sigma$ is the Prandtl number, and $\backslash \; \backslash zeta$ is the magnetic Prandtl number. The Chandrasekhar number is thus defined as:〔N.E. Hurlburt, P.C. Matthews and A.M. Rucklidge, "Solar Magnetoconvection," ''Solar Physics'', 192, p109-118 (2000)〕 :: $\backslash \; =\backslash \; \backslash frac^2\; d^2\}$ where $\backslash \; \backslash mu\_0$ is the magnetic permeability, $\backslash \; \backslash rho$ is the density of the fluid, $\backslash \; \backslash nu$ is the kinematic viscosity, and $\backslash \; \backslash lambda$ is the magnetic diffusivity. $\backslash \; B\_0$ and $\backslash \; d$ are a characteristic magnetic field and a length scale of the system respectively. It is related to the Hartmann number, $\backslash \; H$, by the relation: :: $Q\backslash \; \backslash \; H^2\backslash$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chandrasekhar number」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
