TY - JOUR TI - The numerical thermodynamic analysis of Otto-Miller Cycle (OMC) AU - Çakır Mehmet JN - Thermal Science PY - 2016 VL - 20 IS - 1 SP - 363 EP - 369 PT - Article AB - This paper presents a thermodynamic analysis for an irreversible Otto-Miller Cycle (OMC) by taking into consideration heat transfer effects and internal irreversibilities resulting from compression and expansion processes. In the analyses, the influences of the miller cycle ratio, combustion and heat loss constants and inlet temperature have been investigated relations with efficiency in dimensionless form. The dimensionless power output and power density and thermal efficiency relations have been computationally obtained versus the engine design parameters with respect to combustion and heat transfer constants. The results demonstrate that the heat transfer and combustion constants have considerable effects on the cycle thermodynamic performance. This situation theoretically verified for OMC.
