WebNov 15, 2007 · Dynamo action can fail at very large variation, where strong thermal winds disrupt the mechanism in this regime. If the Rayleigh number is too close to critical the dynamo can fail for low lateral variation, where the flow has a larger component driven by the boundary condition. Similarly, increased azimuthal flow at lower Prandtl numbers … WebJan 5, 2024 · The Dynamo Effect. All of the most luminous objects in the Universe, such as quasars, supernovae, and gamma-ray bursts, are powered by accretion, that is the infall of matter onto a central compact object such as a black hole. In order for matter to accrete inwards, the angular momentum of the material must be transported outwards to slow its ... WebDec 23, 2011 · Our experiments also showed that stronger dynamo action required a higher value of α to still quench the dynamo growth. We validated the saturation mechanism through the negative feedback by removing the imposed field from the already weak case (Fig. 2, case d).

"WebApr 30, 2024 · Summary. The solar dynamo is the action of flows inside the Sun to maintain its magnetic field against Ohmic decay. On small scales the magnetic field is seen at the solar surface as a ubiquitous “salt-and-pepper” disorganized field that may be generated directly by the turbulent convection. On large scales, the magnetic field is … " - Dynamo action
