/ 35 NOZZLE INTERFACE The ow conditions predicted at the nozzle orifi ce eit plane are recorded during the AVL FIRE™ injector ow simulation and serve as input for AVL FIRE™ in-cylinder mixture formation and combustion simulations. That way, a perfect correlation can be established etween the ow conditions inside the nozzle and the conditions under which fuel enters the combustion chamber. This correaltion also takes into account the non-uniform ow out of the injector. EROSION MODELING Cavitation in injection nozzles often causes material erosion and is strongly related to the durability of injection components. Prediction of erosion proaility helps to defi ne the design parameters of the nozzle in order to decrease the ow aggressiveness in critical areas and assure the best possible break-up of the fuel discharged into the combustion chamber or into the port.
