| Abstract: | We construct a d -dimensional eddy damped quasi-normal Markovian (EDQNM) closure model to study dynamo action in arbitrary dimensions. In particular, we find lower d L and upper d U critical dimensions for sustained dynamo action in this incompressible problem. Our model is adaptable for future studies incorporating helicity, compressible effects and a wide range of magnetic Reynolds and Prandtl numbers. [ABSTRACT FROM AUTHOR] |
