Research for the Flow Profile In the Natural Gas Pipelines by Means of PIV
Abstract
The flow profile in the natural gas pipelines can be measured by means of the Particle Image Velocimetry (PIV) to research effects of typical flow profile on gas flow measurement accuracy. Then the measurement accuracy can be improved by compensation. But there is rarely public report about this kind of examples up to know. In this case of test, safety is very important, for example, zero leaking and explosion prevent should be take account. In this paper the PIV system is introduced in detail. The unique design and production of a visual pipeline-section, a positive pressure ventilating room and a high-pressure particle inject device are introduced. Meanwhile the software of PIV system also was represented including some special image processing algorithms and Topological Graph Theory Algorithms.
