Abstract
It was proposed that Manhattan distance method was used for detecting velocity of solid particle in gas-solid two-phase flow, and detection principle was introduced. A delay estimation algorithm was proposed to save data storage space of processor. An experimental system was built and collected signals by oscillograph were analyzed by cross-correlation theory detection method and Manhattan distance method separately. The analysis result shows that Manhattan distance method has better stability and reliability.
