The contribution reviews the research activities on modeling the fuel spray formation in combustion chamber of Diesel engines. A fully Eulerian code has been developed for computing the two‐phase flows of drops dispersed in gaseous environment. Both the multi‐component compressible gas and the drops are described using governing equations written in Eulerian coordinates. The basic laws of conservation are balanced on finite volumes with arbitrary movable boundaries. This facilitates the modeling of movable boundary problems (e.g. computations with moving engine piston). The model features full coupling between both phases in mass, momentum, and energy equations. The drop size distribution in sprays is taken into account using the multi‐continua approach. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
