Description
  • The numerical modelling of hydromagnetic dynamos in a rotating spherical shell using the control volume method is presented. The influence of non-uniform stratification and viscosity on hydromagnetic dynamo action has been investigated. The results indicate that the influence of non-uniform stratification of a spherical shell on hydromagnetic dynamos in the present geometric configuration is noticeable. Convection is columnar and runs in both stably and unstably stratified sublayers, although it is slightly suppressed in the stably stratified region. The generated magnetic fields are mostly dipole dominated. Temperature, pressure, velocity and magnetic fields are significantly modified mainly close to the outer boundary.

  • Prezentujeme numerické modelování hydromagnetických dynam v rotující sférické vrstvě použitím metody kontrolních objemů. Analyzovali jsme vliv nehomogenní stratifikace a viskozity na činnost hydromagnetického dynama. Výsledky naznačují, že vliv nehomogenní stratifikace sférické vrstvy na hydromagnetická dynama je v dané geometrické konfiguraci výrazný. Konvekce je sloupcová a běží v obou podvrstvách, stabilně a také nestabilně stratifikované podvrstvě, přičemž je v stabilně stratifikované podvrstvě slabě potlačována. Generovaná magnetická pole jsou většinou dipólově dominantní. Teplota, tlak, rychlost a magnetická pole jsou výrazně modifikována hlavně poblíž vnější hranice. (cs)
