الملخص EN

An experimental study on air-water two-phase flow under vibration condition has been conducted using double-sensor conductivity probe.

The test section is an annular geometry with hydraulic diameter of 19.1 mm.

The vibration frequency ranges from 0.47 Hz to 2.47 Hz.

Local measurements of void fraction, interfacial area concentration (IAC), and Sauter mean diameter have been performed along one radius in the vibration direction.

The result shows that local parameters fluctuate continuously around the base values in the vibration cycle.

Additional bubble force due to inertia is used to explain lateral bubble motions.

The fluctuation amplitudes of local void fraction and IAC increase significantly with vibration frequency.

The radial distribution of local parameters at the maximum vibration displacement is specifically analyzed.

In the void fraction and IAC profiles, the peak near the inner wall is weakened or even disappearing and a strong peak skewed to outer wall is gradually observed with the increase of vibration frequency.

The nondimensional peak void fraction can reach a maximum of 49% and the mean relative variation of local void fraction can increase to more than 29% as the vibration frequency increases to 2.47 Hz.

But the increase of vibration frequency does not bring significant change to bubble diameter.
