dc.description.abstractA thermal management analysis for the two double loop coolant circuit cases, which used separated cooling structures for the head and block, was performed in the current study. With the conventional configuration, the problem of over cooling problem in the specific components arose, because the cooling system was constrained by the thermal limitations of specific components requiring-high cooling loads. An integrated engine thermal management model was developed to observe features of the proposed structure, which was validated with experimental data, and a semi-iteration process was conducted using a 1D high-frequency engine model. To maximize the advantages of the proposed structure, two electric devices were applied to the ETM model to facilitate "smart cooling." The current analysis indicated that the 30% flow rate of the basic system satisfied the thermal limitations of the target engine under half load conditions; hence, the thermal efficiency increased because of the decreased auxiliary power, friction and heat transfer loss. In addition, it was noted that the thermal deviation in an engine and warm-up time diminished because of the structural changes and optimal coolant control. (C) 2014 Elsevier Ltd.
