This study examines the complex interplay of utopian vision, embodied experience, and social change within the context of modernistic religious architecture. Using Manfred Tafuri's critique of architectural utopianism (1976) and Giorgio Agamben's potentiality theory (2004) as a framework, the thesis analyzes two seminal structures: Peter Zumthor...

Architecture is a blend between art and science. It is a science and very rational in the way that the design solution has to work logically, structurally and rationally in terms of the organisation of space in relation to its function. There are many different design solutions to an architectural brief and the creative nature of working on the...

Actuator line modeling of wind turbines requires the definition of a free-stream velocity in a computational mesh and a regularization kernel to project the computed body forces onto the domain. Both choices strongly influence the results. In this work, a novel velocity sampling method—the so-called effective velocity model (EVM)—is...

This thesis investigates the implementation of three-dimensional nudging into large-eddy simulation (LES) to assimilate observed atmospheric data into an LES model. 3D-nudging 'pushes' the thermodynamic fields in a simulation towards the desired observed fields. The aim is to test if such a method is useful in improving solar forecasts of...

As the urge to decarbonise the energy field becomes increasingly important, a growing interest is shown in wind turbine technologies. In particular, the past few years have seen the development of floating offshore wind turbines for applications in deep waters.<br/><br/>In addition to the harsher environment they are facing, these wind turbines...

Large scale wind farms consisting with floating offshore wind turbines (FOWTs) will be a solution for offshore wind energy industry to access more wind resources. However, wake structures and wake interactions of FOWTs subject to motions are still not yet been fully understand, especially when they are under turbulent inflow conditions with...

This thesis contains case studies of architect-duo’s Alvar and Aino Aalto, Charlotte Perriand and Le Corbusier, and Charles and Ray Eames, that will be used to find out why they designed furniture as architects. This will give more explanation on why an architect would or should design furniture. The thesis shows that the architects have...

Le Corbusier had a big influence on architecture with his modernistic approach and style. A big inspiration for him was the car and how they were mass produced and standardized, initiated by Henry Ford with the Model T. Inspiration of car design can be seen in his architectural approach and designs. This fascination led to him entering an...

Pollution in urban environments is increasingly becoming a major concern for our societies which, together with the increasingly powerful capabilities provided by computational fluid dynamics (CFD), has made pollution dispersion a common topic of research during the last two decades. Several factors are relevant to the dispersion of pollutants...

The development of new wind farm control strategies can benefit from combined analysis of flow dynamics in the farm and the behavior of individual turbines within one simulation environment. In this work, we present such an environment by developing a new coupling between the large-eddy simulation (LES) code GRASP and the multiphysics wind...

Formic acid production from CO<sub>2</sub> allows the reduction of carbon dioxide emissions while synthesizing a product with a wide range of applications. CO<sub>2</sub> hydrogenation is challenging due to the cost of transition metal catalysts and the toxicity of the transition elements. In this work, the thermodynamic confinement effects...

Large eddy simulation paradigm is employed to analyse the internal flow field of a lean premixed swirlstabilized combustor with axial air injection at both non-reacting and reacting conditions for a methane and a methane-hydrogen fuel mixture. The Thickened Flame combustion model with the kinetic mechanism GRI 3.0 and the detailed chemical...

An accurate estimation of gas turbine nozzle guide vane metal temperature locally on its surface is crucial for predicting vane lifetime. The stagnation region at the vane leading edge is, typically, exposed to the highest thermal load, thus, the showerhead configuration of film cooling is often applied on the leading edge. Widely used lean-...

In this thesis, it is being examined how music influenced the design strategy of two renowned architects: Le Corbusier and Steven Holl. The projects that are analyzed regard the Philips Pavilion in Brussels (1958) and the Stretto House in Dallas Texas (1989-1992). The design of the Philips Pavilion followed from a number of concept try-outs that...

The projects: Plan Voisin, Broadacre City and Futurama, of the three architects: Le Corbusier, Frank Lloyd Wright and Norman Bel Geddes, are all three based upon the criticism the architects had on the design of their contemporary city’s and the mobility within these urban structures. The coming up of the automobile had consequences for the city...

A wall resolved LES simulation of the Anti-Fairing wing/body junction introduced by Belligoli et al. [6] to reduce interference drag is performed. The LES mesh is composed of 61.7 million cells with a C-fitted grid around the wing . The simulation is performed using the pimple solver of Open- Foam 4 with a time and space varying inlet boundary...

We report on the application and comparative assessment of two rational turbulence modelling approaches for the computer simulation of air flow and pollutant dispersion in real urban environment: a stand-alone unsteady Reynolds-averaged Navier-Stokes eddy-viscosity model (URANS), and its blend with Large-eddy simulations (LES) in a hybrid...

In the present study, we have performed a series of numerical simulations of the turbulent liquid metal flow in a laboratory-scale setup of the continuous casting. The liquid metal flow was subjected to an external non-uniform magnetic field reproducing a realistic electromagnetic brake (EMBr) effect. The focus of this research was on the...

Atmospheric delay has a profound impact on synthetic aperture radar (SAR) interferometry, inducing a spatial signal that significantly devaluates interferometric products. While the wide-scale variability of the atmosphere can be adequately modeled with global or regional weather models, it is especially the turbulent and convective part of the...

To meet current renewable energy demands, there is a major increase in global wind power capacity. Wind turbines are commonly clustered in wind farms. When operating, wind turbines extract energy from the wind, creating a region characterized by a low velocity, called the wake. The wake negatively impacts the power production of downstream wind...
