摘要:

Numerical simulations of dynamo action are presented for a fluid stirred by a body force such that in the absence of the magnetic field, an ABC flow (to be viewed as the superposition of three helical modes of same wavenumberk0), establishes for kinetic Reynolds numbers below a critical value.
