The influence of spanwise traveling transversal surface waves on the near-wall flow field of turbulent boundary layers with and without adverse pressure gradient is investigated by particle-image velocimetry (PIV) and micro-particle tracking velocimetry (μ-PTV). A detailed analysis of the velocity profile immediately downstream of the actuated...conference paper

Li, J. (author), Tian, Y. (author), Cassidy, M.J. (author)Natural soil is one of the most variable materials as a result of physical and chemical changes. The variation in soil properties significantly affects the failure mechanism and bearing capacity of a footing. This effect is further complicated by considering the spatial correlation of the soil properties. The purpose of this study is to...conference paper

Jing, H. (author), Li, C. (author), Zhou, B. (author)In this paper, some five-point finite difference schemes for steady convection-diffusion problems are presented. To begin with, we use the finite volume method (FVM) to discretize the convection-diffusion equation. After that, we present two five-point difference schemes for the approximation of the first order derivatives on faces, one of which...conference paper 2006

Tessicini, F. (author), Li, N. (author), Leschziner, M.A. (author)The focus of the paper is on the performance of an approximate 'zonal' near- wall treatment applied within a LES strategy to the simulation of flow separating from a three-dimensional hill at high Reynolds numbers. In the zonal scheme, the state of the near-wall layer of the flow is described by parabolized Navier-Stokes equations solved on a...conference paper 2006

Minchin, E. (author), Li, X.X. (author)The traditional system of design-bid-build has long been the principal delivery system for horizontal construction; it has been employed by all the transportation departments in the United States for almost a century. The shift toward design-build (DB) as a time saving method has been successful in many ways, but use of the system has exposed...conference paper 2011

Ying, Shen (author), Guo, Renzhong (author), Li, Lin (author), van Oosterom, Peter (author), Ledoux, Hugo (author), Stoter, Jantien (author)In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant...conference paper 2011

Guo, Renzhong (author), Li, Lin (author), He, Biao (author), Luo, Ping (author), Ying, Shen (author), Zhao, Zhigang (author), Jiang, Renrong (author)A rapid urban growth in China urges to extend land use to land space use in three dimensions due to limited land resource in cities. 3D cadastre is emerging as an effective means to support such a demands for using urban land in a way of three dimensions. Shenzhen, located in the south-eastern coastal region of China, as one of the most...conference paper 2011

The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides ?-Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only ?-Al2O3 is formed, but full...conference paper 2013
