On the turbulence modeling and conjugate heat transfer study of the cooling system of the Beam Dump Facility target at CERN: Steady and Transient analysis

The Beam Dump Facility (BDF) is a new fixed target facility proposed to be installed in the North Area of CERN. Currently in its design phase, the BDF is aimed at the Search for Hidden Particles (SHiP) experiment, which purpose is to investigate the origin of dark matter and other lightly interacting particles. The BDF target/dump sits at the...

Offshore transport, conditioning and storage of Carbon Dioxide: A comprehensive method to evaluate the suitability of existing offshore infrastructure for the transport and storage of carbon dioxide

This report presents the first simple and comprehensive method to effectively compare different infrastructure configurations for reservoirs that have been found suitable for long-term storage of carbon dioxide. Modelling the different transport phenomena along the chain, this study identified a fixed set of input parameters and used them to...

Numerical study of heat transfer in two-phase flows

Heat transfer in multiphase flow plays an important role in nature and in numerous industries such as petrochemical, automotive, food processing, ocean engineering etc. It is becoming increasingly crucial to design more efficient industrial systems to reduce the environmental impact of industrial activities because of global warming and growing...

Optimization of a District Heating Network with the focus on heat loss

In the Netherlands most houses and buildings are connected to a gas network since the nineteen seventies to heat our houses and cook. In march of this year the new Dutch government announced that to meet the climate accord of Paris all dutch household should be of the gas net in 2030. To do this multiple alternatives to heat homes are available...

The applicability of heat flux sensors in a falling film evaporator: Experimental approach

The production process of milk powder consists of multiple stages. This report focuses on the falling film evaporator, which role in the production process is to evaporate the water content from the milk. A falling film evaporator is a large vertically-placed vessel whereby the inside is filled with smaller tubes. Steam enters the vessel and...

Selective Catalytic Reduction for Marine Applications: Dynamic Modelling and System Integration

Environmental regulations are continuously raising the bar towards more advanced diesel engine designs ca- pable of minimizing the emissions of polluting substances. The recent IMO Tier III legislation, entered into force in 2016, is forcing the engine manufacturers to meet a NOx reduction of more than 70% from Tier II for all the ships sailing...

DNS study of scalar transport in a compressible turbulent jet

Direct Numerical simulations (DNS) belong to the class of simulations that strive to emulate the real physical flow by trying to simulate the complete range of scales involved in the flow. Though the computational power has steadily increased in the past few decades, resolving the complete range of scales from the largest scales up to the...
