Summary:

In cylinder gas motion of an open chamber diesel engine is modeled via a newly developed non-isotropic turbulent flow approach. The theoretical treatment is based on the turbulent kinetic energy-dissipation-random model of Reynolds stress (k - ε - R) which incorporates the non-isotropic fluctuating characteristics of gas movement during a compression stroke of a direct injection diesel engine. The validity of the model was compared to the experimental measurement obtained on an axisymmetric reentrant bowl chamber engine configuration. The experimental data fit much more closely to the established non-isotropic behavior in contrast to the traditional isotropic approach
