Energy cascades in driven granular liquids: a new universality class?: I. Model and symmetries
Abstract
Abstract This study deals with the existence and scaling of an energy cascade in steady granular liquid flows between the scale at which the system is forced and the scale at which it dissipates energy. In particular, we examine the possible origins of the breaking of the Kolmogorov Universality class that applies to Newtonian liquids under similar conditions. To answer these questions, we build a generic field theory of granular liquid flows and, through a study of its symmetries, show that indeed there is a possibility that the Kolmogorov scaling is broken, although most of the symmetries of the Newtonian flows are preserved. However, a formal proof of this statement is not yet available.
