By imitating the jetting flow feature of shark gills，a bionic jetting model is established by arranging round outlets on a flat plate. The drag reduction effect under different jetting directions are explored using numerical simulation method when the main flow…

From the view of bionic, optimizing and engineering the corrugated bionic needle with polynomial regression. The results showed that; the width of the ripple with quadratic effect plays a major role in reducing resistance; the impact of non-smooth structure’s spacing…

Swordfish is the fastest fish in the world, which can reach a high speed of 110km/h. Depending on the swing of the caudal fin, swordfish gets the power of swimming. The caudal fin of the swordfish shows crescent and wide…

Constructing the accurate digital model of vessel networks is critical to vascular tissue engineering, in which the segmentation of vessel plays an important role. However, the existing segmentation methods are not able to achieve the goal of accurate segmentation of…

The experimental system used in this study was equipped with sensors and computer-controlled processing technology. This system was used in the measurement of major performance parameters such as pressure, flux, spray angle, spray distribution character of the nozzle and its…

A quaternionic mass defining longitudinal mass () and transverse mass () of a particle is introduced. The longitudinal and transverse masses represent the mass of the particle and matter wave accompanying it, respectively. A massive particle is found to have…

Mesoporous activated carbon prepared from sunflower seeds husks (SSH) using physiochemical activation (potassium hydroxide treatment and carbon dioxide gasification). The optimum conditions for preparing activated carbon from (SSH) were found to be activation temperature of 500 oC, activation time of…

Bionic non-smooth structures on the bodies of revolution had characteristic of drag reduction. In this paper, oil flow visualization test were made in low speed wind tunnel between two bionic non-smooth surface models and smooth surface model. The results show…

This paper extracts the frigate bird’s leading edge contour by CATIA on the basis of the obverse and side pictures when frigate bird glides. Then three bionic wingspans of bending update, forward and integrating the two are built combining NACA…

In this work new type of composite materials for application as coatings for intramedullary implants in the field of orthopaedics and traumatology is offered. Method is based on ability of fluoropolymers to act as biologically inert binding agent and ability…
