DOI: 10.1007/s10494-017-9837-7
Abstract: Direct numerical simulations (DNS) of a hot combustion product jet interacting with a lean premixed hydrogen-air coflow are conducted to fundamentally investigate turbulent jet ignition (TJI) in a three-dimensional configuration. TJI is an efficient method… read more here.

DOI: 10.1016/j.physd.2020.132333
Abstract: Abstract Turbulent jet flows exhibit Kelvin–Helmholtz type of instabilities at its onset. Using a Galilean transform, the Navier–Stokes equation leads to an explicit, solvable expression for the Reynolds stress gradient, which is verified through comparison… read more here.

DOI: 10.1177/09544100221077465
Abstract: Supersonic turbulent high-pressure jet flows, which are discharging in low-pressure quiescent ambient, are recognized as imperfectly expanded turbulent jet. Steady-state imperfectly expanded jet flow has been already studied analytically; however, the transient flow has not… read more here.

DOI: 10.1177/14680874211064677
Abstract: The Turbulent Jet Ignition is an effective concept to achieve stable lean burning for natural gas engines due to the multiple ignition sources, high ignition energy, and fast combustion rate. A variation of the ignition… read more here.
