abstract="In this work, the explosion characteristics of an aluminum (Al)-diethyl ether (DEE)-air mixture were investigated in a 20 L spherical vessel. The effect factors of the explosion characteristics considered were fuel concentration, component proportion, and ignition energy. With the increasing concentration of the mixed fuel (Al/DEE = 1:1), the maximum pressure (P (max)), the maximum rate of pressure rise ((dP/dt)(max)), and the flame propagation speed (ν(F)) exhibit an inversely &quot;U-shaped&quot; curve. The maximum P (max), (dP/dt)(max), and ν(F) values are 901.2 kPa, 148.3 MPa/s, and 15.3 m/s, respectively, corresponding to an optimum concentration of 600 g/m(3). The P (max), the (dP/dt)(max), and the ν(F) increase with the addition of DEE when the proportion of DEE is below 55% but have a decrease tendency when the proportion of DEE is over 55%. As the explosions of Al and DEE were mutually promoting, the studied explosion characteristics of the Al-DEE-air mixture are obviously higher than those of pure Al or DEE in air. The minimum ignition energy (MIE) of the Al-DEE-air mixture is 1.9 mJ, between the MIE of Al and DEE. With the increase of ignition energy, P (max), (dP/dt)(max), and ν(F) all increase, while the minimum explosion concentration presents a linear decreasing trend. This work could provide significant scientific evidence for evaluating the explosion risk of the Al-DEE-air mixture.<p /> <p>Language: en</p>",
