Advanced models of reacting flows in reciprocating

The unsteady, two-phase and reacting flaws under high intensity of turbulence and presence of moveable walls are specific for reciprocating internal combustion engines (ICE). Besides velocity fields, the knowledge of concentration, temperature and turbulent transport coefficients is necessary to estimate the local and average rate of chemical reactions, aiming to optimize thermal. efficiency and pollutant formation. Moreover, the complicated macrostructures of supercharged engines (reciprocator with variable-volume, diabatic-walls, 3D working space, 3D valve ports and manifolds, a compressor and turbine, a charge-air cooler, mixture-formation devices etc.) should be considered due to their mutual. interactions. Such model is presented in the following.
