Influence of Key Structural Parameters of Combustion Chamber on the Performance of Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Investigation on Aggregate Adhesion Segmentation Method in an Asphalt Concrete Digital Image
Publisher: American Society of Civil Engineers
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 ...
Underwater Acoustic Manipulation Using Solid Metamaterials With Broadband Anisotropic Density
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
The Sensitivity of Inner Nozzle Flow in Gasoline Direct Injection Injector to the Nozzle Geometry Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Smoothing Rotary Axes Movements for Ball-End Milling Based on the Gradient-Based Differential Evolution Method
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
