Turbulence effects on the autoignition of DME in a turbulent co-flowing jet
(
Elsevier
, 2017 , Article)
Dimethyl ether (DME) autoignition in turbulent co-flowing jets with preheated air is studied using the one-dimensional turbulence (ODT) model. We investigate the effects of molecular and turbulent transport on the autoignition ...
