Explosion of Undried and Dried Rice Flour with Ignition Time of 20 ms

In this work, the explosion characteristics of rice flour towards difference concentration at ignition time of 20 ms were analyzed. A series of experiments were performed in a 20 L spherical chamber to obtain a maximum overpressure (Pmax), rate of the pressure rise (dP/dT), and deflagration index (K...
