Dimitriou, E.D. (author)
A three-dimensional thermo-fluid model coupled with electrochemical reaction for an anode-supported planar SOFC has been developed to investigate the internal processes and temperature distribution within a single cell unit for the design proposed by the Energy research Center of the Netherlands (ECN) in cooperation with TU Delft. The SOFC...

The main aim of the research is to passively use the on-site energy to create passive climate comfort. Usually this these passive strategies are not integrated into the design process but added to the building design later on when the building design is already finalized. The main topic of this building technology research is to integrate...

The goal of this thesis is to contribute to the understanding of the method CFD by engineers in determining wind loads on structures and ideally contribute to the development of a future design tool. The field of wind engineering is explored and wind tunnel and CFD modelling is discussed. Results determined with wind tunnel tests and CFD...

In this thesis a numerical investigation was performed to increase our understanding of a low Reynolds number transition behind a zigzag trip. This was done with the use of Direct Numerically Simulation (DNS). This means that the Navier-Stokes equations are solved numerically without any use of a turbulence model. The DNS solver of the CFD...

In the SIMMAN 2008 workshop, the capability of CFD tools to predict the flow around manoeuvring ships has been investigated. It was decided to continue this effort but to extend the work to the flow around ships in shallow water. In this paper, CFD calculations for the KLVCC2 are presented. The aim of the study is to verify and validate the...

Hydrodynamic processes largely determine the efficacy of drinking water treatment systems, in particular disinfection systems. A lack of understanding of the hydrodynamics has resulted in suboptimal designs of these systems. The formation of unwanted disinfection-by-products and the energy consumption or use of chemicals is therefore higher than...

The keel of a sailing yacht has been shown to constitute a significant part of the overall resistance. Where the details of this effect are not yet fully understood, Computational Fluid Dynamics (CFD) analysis might reveal mechanisms unseen to the experimental eye. An important step in CFD application is the simulation of a number of validation...

Renewed interest in propeller propulsion on aircraft configurations combined with higher propeller loads lead to the question how the effects of the propulsion on model support disturbances should be accounted for. In this paper, the determination of engine power effects on support interference of sting-mounted models is demonstrated by a...

Two transported PDF strategies, joint velocity-scalar PDF (JVSPDF) and joint scalar PDF (JSPDF), are investigated for bluff-body stabilized jet-type turbulent diffusion flames with a variable degree of turbulence–chemistry interaction. Chemistry is modeled by means of the novel reaction-diffusion manifold (REDIM) technique. A detailed chemistry...

We study flow and heat transfer to a cylinder in cross flow at Re = 3,900–80,000 by means of three-dimensional transient RANS (T-RANS) simulations, employing an RNG k???? turbulence model. Both the case of a bare solid cylinder and that of a solid cylinder surrounded at some fixed distance by a thin porous layer have been studied. The latter...

In Aerospace Engineering the field of Computational Flow Dynamics (CFD) studies the aerodynamic behaviour of aircrafts. What is currently being used to perform CFD simulations are Computer Aided Design (CAD) models of the airplanes, which are usually low-detail industrial design models. Research of new methods for improving the results of the...

Dual-fluid flows are utilised extensively in microfluidics applications. A problem of particular interest isthe precise positioning of the contact discontinuity between the carrier fluids. The paper presents a computational study of the interface positioning in xylene/water flows used in polymer membrane fabrication in microfluidics. Both...

Thermal batteries are primary disposable systems specially designed to develop a high energy density in during a short period. Differently from the classical electrochemical systems, the electrolyte of such batteries is solid at room temperature, which make them inert until they are heated to high temperatures (around 500ºC), when the...

Local heat transfer from a cylinder in tube bank has been extensively studied. In many applications such as design of heat exchangers, detailed information regarding the circumferential and longitudinal variation of heat transfer to a cylinder is required. There are many different methods for measuring local heat transfer like techniques using...

In the past decade, the computational fluid dynamics (CFD) community has put increasing attention on incorporating complex chemistry and physics into CFD simulations. However, for many practicing engineers today there is still much lacking in the effectiveness of reacting-flow simulation. Particularly in the area of combustion, the results can...

This paper analyses the performances of adapted URANS and DES turbulence^modelling for high-Reynolds 2D and 3D aerodynamic flows with a pronounced periodic character. The flow configurations is the NACA0012 airfoil in pitch (experimental test-case by Mc Croskey & Mc Alistair, 1976) at Reynolds number 0.98x10^6, as well as the inherently unsteady...

A systematic grid convergence study is conducted for the Detached-Eddy Simulation (DES) of the massively separated flow around a NACA0021 airfoil at high angle of attack. In order to study the convergence characteristics of DES/LES problems, velocity fields using a series of grids must be generated that demonstrate sufficient dynamic similarity...
