Abstract: Two low-dimensional models for nonlinear dynamo action in Rayleigh-Bénard convection in presence of rigid body rotation about vertical axis are constructed for metallic fluids with finite magnetic Prandtl number (Pm) and small (or zero) thermal Prandtl number (Pr). Dynamo effect is seen for Pm≥0.75 with Pr=0.025 and Taylor number, 0Keywords: Dynamo effect; Magneto-convection; Low dimensional model (search for similar items in EconPapers)
