Abstract
A survey of spray literature has been carried out in order to find all those works containing a theoretical or experimental correlation of spray penetration variables. Twelve such works were found.
Three hypothetical sets of conditions based on actual data from the Sulzer LVA24 diesel engine are used to test the correlations.
The results obtained from applying the three sets of conditions are given as penetration-time curves.
The effects of injection pressure, air density, and nozzle orifice diameter on the penetration predicted by each correlation, are also shown in penetration-time curves.
An analysis of the results leads to several conclusions from which recommendations are made as to whether each correlation is suitable for use under conditions prevailing in modern diesel engines. Future trends in medium speed diesel engine conditions show that all but two of the twelve correlations will not give satisfactory predictions of penetration under these conditions.
