Investigation of Interaction Between Swirl and Jets in Direct Injection Diesel Engines Using a Water Model 770412

Injection of water into water, using an indicator dye for flow visualization, is used to represent the mixing of a fuel spray in swirling air in a Diesel engine. Effects of changes in swirl and jet penetration parameters are shown. Dimensionless groups of variables are derived which may be used to match injection equipment to a combustion chamber.
