Assessment of Models for Near Wall Behavior and Swirling Flows in Nuclear Reactor Sub-system Simulations

Accurate simulation of turbulence remains one of the most challenging problems in nuclear reactor analysis and design. Due to limitations in computing resources, Reynolds averaged Navier Stokes models (RANS) continue to play an important role in reactor simulations. The Consortium for advanced simulations of light water reactors (CASL) is a...

The Applications and Practices of 3D Cadastre in Shenzhen

As the economy and urbanization develop, the expansion of the city not only develops towards the horizontal space, but also towards the vertical space. Facing the development of three-dimensional (3D) space, the traditional two-dimensional (2D) cadastral management mode cannot satisfy the need of current 3D land use and urban plan, so developing...

3D Cadastre Oriented Reconstruction of Administrative Procedure in Chinese Urban Land Management

Focusing on the recent management problem of 3D land utilization in the administrative procedure in China, this paper firstly elaborates the basic characteristics of land ownership and management in China, and then introduces the main concepts and steps in the current urban land management procedure, and reveals the deficiency in supporting 3D...

3D Cadastre in China - a Case Study in Shenzhen City

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...

AMulti-jurisdiction Case Study of 3D Cadastre in Shenzhen, China as Experiment using the LADM

With the increasing urban population, and the urban exploitation and utilization, especially in the subsurface and the air, various spaces above and below each other are built and belonging to different owners or users. Although the traditional 2D cadastre still plays a dominant role in land administration, urban resource and space management,...

The role of three-dimensionality in the development of vortex breakdown in swirling flows

Direct numerical simulations of three-dimensional compressible Navier-Stokes equations are conducted using high-order numerical methods in cylindrical coordinates. Aim of the work is to examine the effect of three-dimensionality in the dynamics of vortex breakdown in swirling jets within a specific range of Reynolds numbers. The main elements of...
