Research on Rapid Response Flow Measurement Technology Based on Laminar Flow Meter

In order to solve the problem that the instantaneous flow of fuel and oxidant in pulse detonation engine is difficult to measure, a rapid response flow measurement technology based on laminar flow meter is proposed. Firstly, the ultimate response speed of laminar flow meter is about 0.1ms by theoretical analysis. Then a new laminar flow channel structure is used to set up the test device, and the uncertainty, linearity and repeatability of the test device are analyzed by using the sonic nozzle gas flow standard device. Finally, the test device is tested with the solenoid valve, and the response speed of the measurement technology is verified.
