“…The modified Woschni equation, on the other hand, agreed well with the experiment despite having a slightly higher maximum incylinder pressure compared with the experiment. In a diesel HCCI engine with a reduced compression ratio, a cool flame phenomenon, which is called the low temperature reaction (LTR), occurred at a temperature below the auto-ignition temperature and created a two-stage ignition, with the LTR and HTR (high temperature reaction) (Kim & Lee, 2007;Neely, Sasaki, & Leet, 2004). The LTR region was found to be advanced for all heat transfer coefficient models at about 340°CA.…”

“…In our study, M equals five since the time scale of the phenomena in the engine operating conditions cannot be bigger than a few crank angle degrees. The absolute fluctuating velocity at a given time and location (U′(θ, i)) is calculated from the square root of the sum of the squares of the fluctuating velocity components: (5) where u′ x (θ, i) and u′ y (θ, i) are fluctuating velocity components calculated from Eq. (2).…”
