Reacting flow near cool walls

Project Details


In the Cool -project, flame-wall interaction (FWI) in a turbulent flow field will be studied. The topic is important since unburned hydrocarbon (UHC) and carbon monoxide (CO) emissions are known to originate from cold near wall regions. As most of the world's energy production will be based on combustion, it is important to develop clean and efficient combustion processes. The challenges in gas engine combustion are 1) poor burning rate of lean methane, and 2) the UHC and CO emissions from cold walls. Our solution to the problem is to use reactivity controlled compression ignition (RCCI) combustion strategy for increased reactivity in the near wall region and B) wall temperature control to minimize the negative effects from FWI. In Cool, we will use detailed chemistry to simulate the igniting/quenching two-fuel mixture. In Cool, we expect to make totally new, radical findings concerning reactivity of two fuels in the near wall region and how it can be controlled for lower emissions.
