摘要：

A computed tomographic scanner using gamma-rays has been implemented for the measurement of void fraction and its distribution in two-phase flow systems such as fluidized beds and bubble columns. The automated scanner is capable of imaging flows in test sections between 2.5 cm and 45.0 cm in diameter. The developed system hardware, the adopted algorithm for image reconstruction and possible sources of error in measurement are discussed. Typical results for void fraction distribution in bubble columns are presented.
