The experimental system included vessel–pipe, gas distribution, data acquisition, and ignition systems. Cylindrical vessels with equal length–diameter ratio were used in the experiment and their volumes were 113 and 11 L. The length of the pipe was 2 m and the diameter of the pipe was 60 mm, with totaling four sections. All these components were connected by flanges. Holes inside the vessels and pipes were used to install pressure transmitters, flame sensors and ignition devices, which could be connected according to the experimental needs. As shown in Figs. 5.1, 5.2 and 5.3, pipes, a vessel connected with pipes, and two vessels connected with pipes were selected; P in the figure represents a pressure sensor, and a flame transducer. The distance between the measuring points was 1200 mm.

摘要

The experimental system included vessel–pipe, gas distribution, data acquisition, and ignition systems. Cylindrical vessels with equal length–diameter ratio were used in the experiment and their volumes were 113 and 11 L. The length of the pipe was 2 m and the diameter of the pipe was 60 mm, with totaling four sections. All these components were connected by flanges. Holes inside the vessels and pipes were used to install pressure transmitters, flame sensors and ignition devices, which could be connected according to the experimental needs. As shown in Figs. 5.1, 5.2 and 5.3, pipes, a vessel connected with pipes, and two vessels connected with pipes were selected; P in the figure represents a pressure sensor, and a flame transducer. The distance between the measuring points was 1200 mm.
