Background In this paper, we used the principle of biomimetics to design two-dimensional and three-dimensional bar sections, and used computational fluid dynamics software to numerically simulate and analyse the aerodynamic noise, to reduce drag and noise. Methods We used the principle of biomimetics to design the cross-section of a bar. An owl wing shape was used for the initial design of the...
Glass forming ability and thermal expansion behavior of nominal compositions Gd 55 Al 25 Cu 10 Co 10 bulk metallic glasses (BMGs) at different melt superheated temperatures were investigated using differential scanning calorimetry (DSC), X-ray diffractometry (XRD), high resolution transmission electron microscopy (HRTEM) and thermal dilatometer. It was found that the...
