| Abstract: | A new method has been developed to measure flowing parameters in a pipe. The method is based on digital image processing techniques, in which an image subtracted algorithm is used to remove the background noise and an iteration algorithm is used to calculate the optimizing threshold.Experimental results show that the method has the capacity of on line measuring of bubble sizes and gas area fraction in gas liquid two phase flow. |
| Keywords: | gas liquid two phase flow image processing bubble parameter measuring |
