ABSTRACT in this paper a CPD-based strategy is used to model two of the dominant ?mdamental characteristics of the two-phase airfoil ?ow ?eld within a bearing chamber; ?rstly the complex three dimensional (3D) air?ow and subsequently the associated motion of oil
AFR and fuel cut-off modeling of LPG-fueled engine based on engine , transmission , and brake system using fuzzy logic controller (FLC)
