Heat transfer in hcci phenomenological simulation models: A review

摘要

This study presents a review of the heat transfer treatment in HCCI phenomenological simulation models, including single-zone and multi-zone ones. Heat transfer within the combustion chamber is significant when modeling the internal combustion engine in general and the HCCI combustion process in particular. It determines to a great extent the temperature field within the combustion chamber throughout the engine operating cycle, and especially during compression and combustion. In HCCI engines, combustion relies upon the auto-ignition of a premixed charge that is present for most if not all of the compression stroke. In this combustion mode the heat transfer process directly affects mean gas and local temperatures, thereby influencing ignition timing, combustion rate and the formation of HC, CO and NOx emissions. The success of any simulation model in describing or predicting the HCCI combustion process and emissions formation evidently depends partly on its ability to reliably predict the heat transfer phenomena involved.
