Abstract: A new method for the voidage measurement of gas-oil two-phase flow was proposed. The
voidage measurement was implemented by the identification of flow pattern and a flow
pattern specific voidage measurement model. The flow pattern identification was achieved by
combining the fuzzy pattern recognition technique and the crude cross-sectional image
reconstructed by the simple back projection algorithm. The genetic algorithm and the
partial least square method were applied to develop the voidage measurement models.
Experimental results show that the proposed method is effective. It can overcome the
influence of flow pattern on the voidage measurement, and also has the advantages of
simplicity and speediness.
