“…The droplet temperature is updated at every time-step by the use of a heat balance which relates the droplet temperature to the convective heat transfer at the droplet surface. The details of the implemented evaporation droplet model into the LES code is given by Olovsson (1993) As the method is transient, new droplets have to be introduced at predetermined intervals. It is not possible to follow every physical droplet and instead so called numerical droplets, or parcels, are used where each parcel has to represent a number of real droplets.…”

The design of a generic experimental LPP-combustor (Lean Premixed Prevaporized) is described. The combustor was tested at inlet pressures between 3 and 7 bar and with an inlet temperature between 500 K and 700 K. Tests were run with Diesel No.2 and Jet A-1 fuels comparing emissions of CO and NOx. The tests showed low NOx and CO values for a range of conditions although difficulties of using the LPP-technique close to the final boiling point of the fuel were encountered. To increase the understanding of the flow situation inside the combustor, numerical simulations using a large eddy simulation code was also performed. The main interest in the calculations was the evaporation process of the liquid fuel.
