Ignition and burning characteristics of single aluminum and magnesium particles are experimentally investigated. Burning time, ignition delay, flame temperature, and ignition temperature were measured. The single metal particle (30-100 μm in diameter) is uplifted by an electrodynamic levitator, exposed and ignited by a CO2 laser. The thermal radiation intensity was measured using the photomulti...
The effect of inlet humidity conditions and inclination angle on the air side thermal hydraulic performance of a brazed aluminum heat exchanger has been investigated experimentally. The crossflow heat exchanger had flat tubes and folded fins with fin and louver pitch of 2.1 mm and 1.4 mm, respectively. The glycol temperature was held nearly isothermal at 1C, while humidity of the 12C inlet air ...
Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...
Abstract In this study, a kind of structural gradient metal hollow spheres composites (SG-MHSCs) were fabricated using two kinds 316L stainless steel with different diameters and A356 aluminum through the casting method. Then density SG-MHSCs was measured by direct measurement; microstructure characterized Scanning Electron Microscope. Meanwhile, acoustic performance MHSCs tested impedance tube...
