摘要：This paper presents a detailed investigation on turbulent burning velocity of diethyl ether (DEE)/air mixtures under different pre-ignition quasi-isotropic turbulence. The concentration of DEE/air mixtures is the equivalence ratio = 1.1. The experimental result of the laminar burning velocity (uL)is 0.55 m/s, and the largest data of turbulent burning velocity (u t) are 1.8 m/s at pre-ignition quasi-isotropic turbulence velocity at 6.2 m/s. In this work the model gives the expression on the laminar burning velocity (UL )and turbulent burning velocity (ut )versus the pre-ignition turbulence velocity Urms in accordance with Williams's theoretical model. ? 2020 Published under licence by IOP Publishing Ltd.
