"Linear Turbulence Model Validation for the Case of In-cylinder Phenomena Modeling"@en . "The presented work deals with in-cylinder process modeling, it concerns a high- pressure phase of a four stroke engine cycle (compression and expansion stroke). The Eulerian approach is applied to a general 3-D case. The major focus of the work is turbulence modeling. Linear one-equation models and two-equation ones based on the Boussinesq hypothesis are applied. A~combustion model is added which deals with flame front propagation by means of solving a transport equation. From the numerical point of view, a finite volume method combined with an explicit multi-stage Runge-Kutta scheme is implemented. The properties of the whole mathematical model are tested and the influence of important input parameters is analyzed. A comparison of measured and computed data is presented as well."@en . "3"^^ .
