The proposed numerical model is based on the Eulerian—Eulerian granular flow modeling with the kinetic theory of granular flow. The model includes the following basic governing equations: the continuity equations of the solid and gas phase, the momentum conservation equations of the gas and solid phase, the energy equations of gas, and the solid phase and conservation equations for chemical components.

The choice of the semi empirical constants of the inter-phase interaction drag force model is significant and these constants must be adjusted for each particular regime of fluidiza- tion. Presented numerical experiments primarily were applied to verification of the assumptions about the impact of water content in a liquid fuel on FB combustion intensity. The numerical experiments, based on the proposed mathematical model, also have been used for the purposes of analyzing the im- pacts of various reactor powers as well as fluidization numbers, on the combustion efficiency and on combustion zone temperature fields.

U ovom radu prikazani su rezultati usporedbe simulacija provedenih na Ottovim motorima, od kojih jedan koristi inovativnu konstrukciju klipnog mehanizma, dok drugi koristi konvencionalnu konstrukciju klipnog mehanizma. In the last few years there has been talk about the harmful effects of exhaust gases coming from internal combustion engines, in order to reduce their emissions we need to increase the engine performance, that is, reduce fuel consumption.
