HANSEN, A. C.. Modelling gas flow in a direct injection diesel engine: II - Turbulence. R&D j. (Matieland, Online) [online]. 1991, vol.7, pp.25-31. ISSN 2309-8988.

Turbulence in the combustion chamber of an engine has a strong influence on combustion characteristics and heat transfer rates. The objective of this investigation was to develop a gas turbulence model applicable to direct injection diesel engines. The model was designed to generate the expected trends that could be ascertained from the limited experimental data available. In addition the model was kept as simple as possible without sacrificing a practical level of accuracy. The output from the model compared favourably with published data in terms of trends and orders of magnitude.
