Buildings, which account for approximately half of all annual energy and greenhouse gas emissions, are an important target area for any strategy addressing climate change. Whilst new commercial buildings increasingly address sustainability considerations, incorporating sustainability technologies in the refurbishment process of older buildings...

Integration of design, engineering and construction (D-E-C) aligned to collaborative networks (CN’s) is about overcoming traditional barriers. Collaborative Network systems are submitted to economic, social and environmental circumstances. D-E-C integration linked to CPFR and submitted to CN’s could bridge traditional barriers, when aligned to...

Watanabe, T. (author)
The oscillation and rotation of a levitated liquid droplet are simulated numerically using the level set method. The frequency and the damping of the oscillation for small amplitude are shown to agree well with those by the linear theory. It is shown that the oscillation frequency decreases as the amplitude increases. The oscillation frequency...

In the pipe flow model of Dwight Barkley the main idea is to model pipe flow as an excitable, bistable medium. Using a one-dimensional FitzHugh-Nagumo-type reaction-advection-diffusion system with two variables the model captures qualitatively a surprising number of features of the turbulence transition in pipe flow. Motivated by this success,...

An experimental study was undertaken to investigate low Reynolds number effects on mixing characteristics and turbulent transport phenomena in the near and intermediate regions of free orifice jets. The cross-sections examined were round, square and ellipse of aspect ratio 3. For each orifice cross-section, detailed velocity measurements were...

One third of the current housing stock in The Netherlands dates from the sixties and seventies and a large part of these dwellings are fairly similar (because they were built in series). There is a high need for smart and speedy renovation methods, to improve technical, energy and cost efficiency of renovation projects as well as to limit...

The aims of the Flexing Wind project, investigated in an intensive cross-disciplinary course, were twofold. First was to learn about aerodynamic phenomena around buildings. Second was to explore ways to observe, measure, and control the negative effects of wind around specific pedestrian areas, tram stops, and public sites in Melbourne City....

The development of new medicines for inhalation requires a series of procedures including in-vitro tests using special testing devices, which simulate the human airways to assess the local deposition of drugs. Such tests require samples of the new drugs and the series of tests are costly and time-consuming. A numerical model for the two-phase...

Rough-wall turbulent channel flow is investigated via time-resolved tomographic particle image velocimetry (TPIV). To facilitate 3D measurements in the bulk flow as well as very close to the rough surface the optical refractive index of the transparent acrylic channel wall is matched with that of the liquid, a concentrated solution of sodium...

Application of nanotechnology in construction industry is a quite new field with many interesting and promising possibilities. Nanosilica self healing properties, based on the high reactivity of these particles with the calcium components of cement, are of great interest in rehabilitation treatments of hardened concrete. In present work, the...

Energy use within the UK domestic sector is on the increase, causing significant environmental and social stresses. This increase in energy consumption is not only due to the rising proliferation of technological devices within the home, but also to their context of use, and the behaviours and habits attributed to and enacted through their...

De Woningwet bestaat inmiddels 110 jaar, maar anno 2011 ziet de wereld er anders uit. Enerzijds is de woningvoorraad sterk gegroeid en is de kwaliteit van woningen en woonomgeving sterk verbeterd. Anderzijds werkt de woningmarkt niet goed en is vastgelopen door alle goedbedoelde maatregelen. Tegelijkertijd zijn bewoners, woningcorporaties,...

A combined wind tunnel and computational study of grid-generated turbulence along the centreline shows that the close to -5/3 power law signature of energy spectra in the frequency domain originates in the production region close to the grid where the velocity derivative statistics become quite suddenly isotropic but also where the turbulent...

This study looks at the spatio-temporal dynamics of the coherent structures found in under-expanded supersonic impinging jets from a circular nozzle at a pressure ratio of 3.4 and standoff distances of 2d and 5d. In these jets the development of coherent structures within the shear layer and their interaction with a standoff-shock are the...

This paper presents the current state of progress investigating the possibility of modelling traditional Chinese architecture using parametrics based on the two rule books. This builds on the work of producing systematic analysis on both rule books and contributing knowledge from extant buildings. The case study target is the floor plan...

Pre-tender estimates are susceptible to inaccuracies (biases) because they are often prepared within a limited timeframe, and with limited information about project scope. Inaccurate estimation of project uncertainties is the underlying cause of project cost overruns in construction. Typically, cost engineers and quantity surveyors would add...

Execution of business processes often requires resources, the use of which is usually subject to constraints. In this paper, we study the compliance of business processes with resource usage policies. To this end, we relate the execution of a business process to its resource requirements in terms of resources consumed, produced or blocked by...
