Numerical simulation of free overfall in a rough channel

Guo, Y. (author), Zhang, L. (author), Zhang, J. (author)

This paper reports the results from a turbulent numerical modelling study on the free overfall in a rectangular channel. A wide range of model parameters (i.e. discrete square bar bed roughness, channel slope, and incoming upstream Froude number) is investigated. The water surface profiles, velocity fields and end-depth are simulated and...

Computation of Modal Radiation through an Engine Exhaust on Adaptively Refined Meshes

Huang, X. (author), Ma, Z. (author), Zhang, X. (author)

This paper outlines the method of a block-structured adaptive mesh refinement (AMR) and its application to the computation of noise radiation from a realistic engine exhaust geometry with flow. The computational model described allows acoustic waves, propagating inside the bypass duct of a generic aircraft engine, to be admitted into a...

Drying Effects on Corrosion Properties of Cr(VI) and Cr(III) Treated Electrogalvanized Steel

Zhang, X. (author), Van den Bos, C. (author), Sloof, W.G. (author), Hovestad, A. (author), Terryn, H. (author), De Wit, J.H.W. (author)

Drying effects on corrosion performance of Cr(VI)- and Cr(III)-treated electro-galvanized steel have been studied in NaCl solution using potentiodynamic measurements and electrochemical impedance spectroscopy (EIS). The Cr(VI) and the Cr(III) treated specimens were dried at three different temperatures: 60, 110 and 210°C. The surface layers were...

Numerical simulation on the mechanical characteristics of double-stranded DNA under axial stretching and lateral unzipping

Yuan, C.A. (author), Zhang, G.Q. (author), Han, C.N. (author), Chiang, K.N. (author), Cui, Y. (author)

The mechanical characteristics of the long-chain double-stranded DNA (dsDNA) molecule under the axial stretching and lateral unzipping are studied by the clustered atomistic-continuum method (CACM). The CACM consisted of the clustered atom method (CAM) and the atomistic-continuum method (ACM). The CAM treats the specific atomic group as the...

Distributed Task Allocation in Social Networks

De Weerdt, M.M. (author), Zhang, Y. (author), Klos, T. (author)

This paper proposes a new variant of the task allocation problem, where the agents are connected in a social network and tasks arrive at the agents distributed over the network. We show that the complexity of this problem remains NPhard. Moreover, it is not approximable within some factor. We develop an algorithm based on the contract-net...

The phosphors Ba3Gd(BO3)3:Ce3+ were prepared by a solid-state reaction technique at high temperature. The vacuum ultraviolet-ultraviolet and visible spectroscopic properties of the phosphors together with decay time curves are investigated and discussed. The spectroscopic properties are explained by occupancy of Ce3+ at two different Gd sites in...
