Abstract: In this paper, a profile design of surface texture was applied for improving the tribological performance of piston ring–cylinder pair. The design of texture pattern was implemented by numerous textures of different depths ...

Abstract: The study of microchannel methanol steam reforming plays an important role in improving the efficiency of hydrogen production and promoting the development of clean energy. This thesis numerically simulates a circle-triangle ...

Abstract: After a diesel engine is fueled with biodiesel, the morphology and oxidation activity of particulate matter will change, which will affect the performance and regeneration effect of the diesel particle filter (DPF). This ...
