Abstract:
Large eddy simulation of turbulent free round jet has been performed to study statistical properties of turbulence, including third-order structure functions. It has been shown the presence of a zone within the jet initial region where the spectral flux of turbulent energy is directed from smaller scales toward larger ones and the longitudinal third-order structure function becomes positive. Energy spectra calculated in this zone demonstrate the E(k) approximately k(-3) law specific for two-dimensional turbulence.

Conservation of Energy in Control Volume
For steady flow systems, the time derivative of the stored energy becomes zero since there is no energy accumulation within the control volume. This simplifies the energy equation to:
