多相流多参数动态非接触集成测量新机理与方法研究

Multiphase flow is one of the important branch of subject of Thermal Physics, it presence widely in the engineering domain of energy sources, chemistry industry, metallurgy, petroleum and aeronautic and astronautic, etc. The measurement theory and it's principles of Multiphase flow is one of the most important question of science and technology, which is in relation to the global entironment and using of energy sources in the 21-century. However, most problems of Multiphase flow measurement in domain of industry and agriculture are not solved. So it is essential to explore new effective detecting technology and it's realization method for developing and solving Multiphase flow problems..This research put forward a multi-parameters and integrated measurement theory and method in Multiphase flow, which based on the fusion of industry process tomography technology and fuzzy correlation theory. The gas-solid two-phase flow is considered as research object, by adopting the optical array sensors which as information collection unit for tube two-phase flow, the distribution image and flow regime of measure flow profile in tube are obtained through the fusion and disposal of the measure optical information, a new means and method is presented for the demand to solve problems in industry, such as the measurement of dust particles discharge, the measurement, energy saving and control in the pneumatic of coal and other bulk particles. .
