The Stuart number (N), also known as magnetic interaction parameter, is a dimensionless number of fluids, i.e. gases or liquids. It is defined as the ratio of electromagnetic to inertial forces, which gives an estimate of the relative importance of a magnetic field on a flow. The Stuart number is relevant for flows of conducting fluids, e.g. in fusion reactors, steel casters or plasmas. ==Definition== : * ''B'' – magnetic induction * ''Lc'' – characteristic length * ''σ'' – electric conductivity * ''μ'' – dynamic viscosity, sometimes denoted as ''η'' * Ha – Hartmann number * Re – Reynolds number 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「Stuart number」の詳細全文を読む スポンサード リンク
