Abstract: AbstractAiming at the problems of low ejection rate, poor hydrogen circulation effect, and complex structure of the mixing pump system of the ejector under the low-power condition of the fuel cell, this paper proposes a ...

Abstract: The structural parameters of combustion chamber have great impacts on the process of air–fuel mixing, combustion, and emissions of diesel engine. The dynamic characteristics and emission performances could be improved by ...

Abstract: The processing method of asphalt mixture digital images was investigated on the basis of the gray – level distribution of asphalt concrete images. Some bond areas were found between different aggregates. The watershed ...

Abstract: A new type of all-solid metamaterial model with anisotropic density and fluid-like elasticity is proposed for controlling acoustic propagation in an underwater environment. The model consists of a regular hexagonal lattice ...

Abstract: The inner-flow of gasoline direct injection (GDI) injector nozzles plays an important role in the process of spray, and affects the mixture process in gasoline engine cylinder. The nozzle structure also affects the inner-flow ...

Abstract: Ball-end milling is widely used in five-axis high-speed machining. The abrupt change of tool orientations or rotary axes movements will scrap the workpiece. This research presents a smoothing method of rotary axes movements ...
