Measurements of the Flow in Backshroud/Casing Clearance of Precessing Centrifugal Impeller
International Journal of Rotating Machinery, 1997 Detailed flow measurements have been made to clarify the unsteady flow in the backshroud/ casing clearance of a precessing centrifugal impeller. The unsteady pressure was integrated to obtain the fluid force moment on the precessing impeller shroud for ...

Stereo PIV measurements of vortex behavior produced by a pitch-oscillating discoid airfoil
Journal of Fluid Science and Technology, 2014 Flying animals and insects flap their wings using a combination of pitching and heaving oscillations. Unsteady fluid forces presumably play an important role in the flight mechanism, and also in the propulsive force of swimmers performing the front crawl.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots
Advanced Robotics Research, EarlyView.This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Unsteady Hydrodynamic Forces on a Lifting Body
Journal of the Society of Naval Architects of Japan, 1990 A numerical method has developed to analyze unsteady hydrodynamic forces of 3D lifting surfaces of arbitrary planform, in which velocity potential is expressed by the doublet distribution over wing surface and the wake. The wing surface is divided into a number of meshes and the strength of the doublet on each mesh is assumed to be constant which makes

Advanced Science, EarlyView.ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...
