abstract = {The energy transfer between different scales of a passive
scalar advected by homogeneous isotropic turbulence is
studied by an exact generalized transport equation for the
second moment of the scalar increment. This equation can be
interpreted as a scale-by-scale energy budget equation, as
it relates at a certain scale r terms representing the
production, turbulent transport, diffusive transport and
dissipation of scalar energy. These effects are analyzed by
means of direct numerical simulation where each term is
directly accessible. To this end, a variation of the Taylor
micro-scale based Reynolds number between 88 and 754 is
performed. Understanding the energy transport between scales
is crucial for Large-Eddy Simulation (LES). For an analysis
of the energy transfer in LES, a transport equation for the
second moment of the filtered scalar increment is
introduced. In this equation new terms appear due to the
interaction between resolved and unresolved scales, which
are analyzed in the context of an a priori and an a
posteriori test. It is further shown that LES using an eddy
viscosity approach is able to fulfill the correct
inter-scale energy transport for the present configuration.},
