The hydrodynamics and flow field was measured using 2-D TR PIV. The convective velocity formulas proposed by Antonia et al. (1980) and Van Doorn (1981) were tested. The turbulent energy dissipation rate estimated independently in both radial and axial directions using the one-dimensional approach was not found to be the same in each direction. Using the proposed correction, the values in both directions were found to be close to each other. The relation ε/(N3·D2) ∞ const. was not conclusively confirmed.}, type={Artykuły / Articles}, title={Local Turbulent Energy Dissipation Rate in a Vessel Agitated by a Rushton Turbine}, URL={http://journals.pan.pl/Content/85035/PDF/02-paper-Sulc.pdf}, doi={10.1515/cpe-2015-0011}, keywords={mixing, Rushton turbine, local turbulent energy dissipation rate, energy spectrum function, fluctuation velocity}, }
