要約

The present work focuses on investigating the dynamics and motion of a bubble rising in a three-dimensional sinusoidal channel. The results are reported for various Reynolds numbers, Bond numbers and channel wall amplitudes. The bubble rise velocity initially increases and then varies periodically with channel height. The peak is attained at the convergent section and the valley at the divergent section. The bubble wobbles as it rises along the channel. The magnitude of bubble wobbling is also found to be low at both small and large channel wall amplitudes.
