3D Cadastre in the Case of Engineering Objects, such as Bridges and Road Viaducts

At present, the implementation of cadastral registration of transport investments (such as railway lines on bridges and on viaducts, roads on viaducts, etc.) is performed in the so-called "layer" system. This means that many objects are constructed at different levels (layers) within the space of a given parcel. Several parties may be interested...

Multiscale modelling of chloride transport in cementitious materials at the atomic and pore network scales

To reduce the CO2 footprint of construction materials, concrete producers blend their cement with Supplementary Cementitious Materials (SCMs). And even though such blended systems are eco-friendlier than the Ordinary Portland Cement (OPC), they are required to respect standards. In this context, understanding and predicting the durability of...

Layer approach to ownership in 3D cadastre – a subway case

The paper focuses on approaches to the registration of real property rights in the case of underground or subway tunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, and Sweden. The Authors made analysis of the current way of registration of rights to subway tunnels in the chosen countries,...

Reliability Analysis of Heterogeneous Slope Considering Effect of Distribution Types

The effect of probability distributions on the slope reliability is highlighted in this study since the lognormal distribution is often used to characterize the variability of soil properties to avoid negative values. A multiple response-surface based MCS method for slope reliability analysis in spatially variable soils is proposed. A...

Turbulent entrainment in a shearless mixing layer at the edge of a cloud

Three-dimensional direct numerical simulations which combine the Eulerian description of temperature, vapor content and velocity with a Lagrangian ensemble of cloud water droplets are used to study the turbulent entrainment and subsequent mixing of clear air with a cloudy air filament. The study is conducted in a shearless mixing layer setup...

Supersonic laminar flow control techniques investigated within the SUPERTRAC project

The global objective of the SUPERTRAC project is to explore the possibilities to delay laminar-turbulent transition on supersonic aircraft wings. The following techniques are investigated: micron-sized roughness elements, anti-contamination devices, suction and shape optimization. This paper provides an overview of the project and describes in...

Simulation of three-dimensional separation with a zonal near-wall approximation

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...

Computing the near-wall region in gas micro- and nanofluidics: Critical Knudsen layer phenomena

In order to capture critical near-wall phenomena in gas micro- and nanoflows within conventional CFD codes, we present scaled Navier-Stokes-Fourier (NSF) constitutive relations. Our scaling is mathematically equivalent to applying an 'effective' viscosity to the original constitutive relations. An expression for this 'effective' transport...

On grid-independence of RANS predictions for aerodynamic flows using model-consistent universal wall-functions

A universal wall-function method for RANS turbulence modelling is presented, which is designed by consistency between the global turbulence model and the near-wall model. This ensures solutions independent of the wall-distance of the first grid node above the wall provided it is located in the logarithmic part of the boundary layer or below. The...

Dwelling from the inside to the outside: Between the private and the public

Workshop 3. Session 3.3: Expression and taste Abstract: Dwelling has boundaries, filters from the inside to the outside. The facade, the skin of the dwelling, is a sensitive part of the house. It has many functions to fulfill: the face of the home as a face to the public, the physical filter and the psychological membrane of the home as well....
