The results for the fine and coarse turnings (figure and 10, respectively) show a clear dependency of the Bodenstein numbers on the oscillatory Reynolds number. For the fine magnesium turnings, Bo decrease with increasing oscillatory Reynolds number (figure ). An average Bodenstein number of 184 was registered for the pulsation-free operation (compare table ). For small oscillatory Reynolds numbers, an increase of Bo by 25 % up to 230 were possible. Correlating Bo to the pulsation frequency and amplitude reveals a decrease with increasing frequency and with increasing amplitude (figures 11 and 12). The scattering of the data points in figure results from the coupled impact of the amplitude and the frequency.
