Ignition and propagation of a reaction front in a counterflow system of an iso-octane/air stream mixing with an exhaust gas stream is computationally investigated to understand the fundamental characteristics of homogeneous charge compression ignition (HCCI) auto-ignition. Various mixing rates are imposed on the system and the effects of dissipation rates on auto-ignition are studied. Ignition ...

Advanced combustion systems that utilize different modes and alternative fuels have significantly improved performance emissions compared to conventional diesel or spark-ignited combustions. As an fuel, dimethyl ether (DME) has been receiving much attention as it runs effectively under low-temperature (LTC) such homogeneous charge compression ignition (HCCI) reactivity control (RCCI). Under com...

Renewable sources and enhancement of energy conversion efficiency are the main paths chosen by European Community to stop climate changes environmental degradation, enable a sustainable growth. For this purpose, construction new more dynamic electricity distribution network is mandatory. This “smart grid” should also include small medium-size companies, able program generation use from renewabl...

Since the 21st century, people's increasing attention to fuel economy and environmental issues has prompted engine research community continuously develop new efficient clean combustion theories methods. In terms of technology, many researchers have proposed different methods, such as homogeneous charge compression ignition (HCCI), premixed (PCCI), reaction controlled (RCCI), which are three ma...

The adverse environmental impact of fossil fuel combustion in engines has motivated research towards using alternative low-carbon fuels. In recent years, there been an increased interest studying the mixtures consisting mainly hydrogen and carbon monoxide, referred to as syngas, which can be considered a promising toward cleaner technologies for power generation. This paper provides extensive r...

In this study, we investigate the effect of different split injection strategies on ignition delay time (IDT) and heat release rate (HRR) characteristics in Reactivity Controlled Compression Ignition conditions via large-eddy simulation finite-rate chemistry. A diesel surrogate (n-dodecane) is injected into a domain with premixed methane oxidiser two separate pulses. Three are investigated by f...
