RIVERO-MEJIA Ingeniería CFD solver Diesel Engine Heat transfer Indicated cycle Predictive model In this paper, a comparative study between numerical simulations and experimental data of the indicated cycle of a direct injection diesel engine is presented. A CFD package and a predictive model were used to simulate several engine operating conditions. Results were compared with experimental data obtained from an engine test bench. The comparison was based on indicated-cycle parameters such as pressure, temperature, heat release, power, efficiency, specific fuel consumption and mean effective pressure. Results show that in all cases simulated cylinder-pressure curves are in very good agreement with the experimental results. For the low-load mode, differences are around 5% at maximum pressure peak. On the other hand, temperature and heat release rate curves present significant differences between simulations and experiments. This could be a consequence of the combustion and heat transfer models used for the simulations. However, it is shown that the use of CFD tools for studying combustion phenomena in diesel engines is highly convenient. 2014 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553756869002 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.1 Vol.13 |
