Experiment Research On Online Detection Of Solid Concentration Of Two-phase Flow By Double Pressure Drop Method

Because of complexity of detection of the parameter of solid-gas two-phase flow, online detection of the parameter of gas-solid two-phase should be an urgently solved problem but it haven't been well solved yet. It has obvious advantage to use resistance pressure drop to measure the parameter of two-phase flow. Based on forerunner's calculation of resistance pressure drop of two-phase flow, the paper utilized the method of combining horizontal straight tube resistance equation and crankled tube resistance equation to get the velocity of the two-phase flow and solid concentration,According to this thought, experiments were held to validate the idea if it can wok .By thorough experiment on the two-phase flow test-pad, it proved to be working. Then numerical simulating calculation was also held to prove the feasibility of the idea. And the result support the idea too. It shows that the way can detect the velocity and solid concentration of the two-phase flow online. Because of its virtues of simpleness and rapid response and non-incursion it has a good prospect in the project uses.
