Ambergy Industrial: A heating control system to save energy

Industrial buildings, used as warehouses or distribution centres, are characterized by large doors which are opened temporarily or for longer periods. A new technique - called Ambergy - is investigated which prevents unnecessary energy loss through open overhead doors in heated industrial halls. This technique consists of a smart coupling...

CFD Modeling of Two-Stage Parallel Plate Sedimentation Centrifuge for Microalgae Dewatering

As one of the most fast growing species on earth, microalgae provides great potential to satisfy the ever increasing demand in food, energy and material in a sustainable way. The focus for this thesis work is on one of the most important bottle neck of microalgae harvest process: microalgae dewatering, by CFD modeling of the flow and...

Analysis and Simulation of an Anode Supported Solid Oxide Fuel Cell Single Channel for Operation with Biosyngas and Methane

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...

Schiphol Interchange Station - Integrated design research for the wind and daylight performance of the building envelope

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...

Testing the application of CFD for building design: Towards a CFD application as a design tool

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...

Numerical study of boundary layer transition behind a zigzag trip

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...

Application of the computational fluid dynamics solver FLUENT to keels of sailing yachts

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...

Laser scanning modelling of a Cessna citation: For Computational Fluid Dynamics (CFD) Studies

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...
