By observing the nature from the circulation through the measurement in the DAOR, stability can also be verified in a click here constant rolling motion at all examined frequencies. The character of the circulation altered most significantly with raising frequency of Al powder. At lessen frequencies, Al powder showed rolling movement and, gradually, even a cataracting motion appeared.
