An Object Storage Solution for Bicycles in Urban Enviroments

The purpose of the thesis was to design an object storage solution that fitted the modern needs of an urban bicyclist. The project was focused on analyzing today’s needs and whether or not these needs were being met by the current object storage solutions. A presumption was made that present day object storage solutions had stagnated in a small number of solutions that were not necessarily fitted

Super adiabatic combustion of carbon-free and carbon-containing fuels

The present work provides a new perspective on super adiabatic combustion (SAC) of fuel/air mixtures involving methane, ethane, propane, butane, heptane, iso-octane, 1-hexene, toluene, ammonia, and hydrogen. The simulations cover the temperature range of 1200–2000 K, initial pressures of 1–50 atm, and equivalence ratios of 0.5–2.0. The detailed chemical kinetic mechanism C3MechV3.5 has been used f

Investigation of turbulent premixed methane/air and hydrogen-enriched methane/air flames in a laboratory-scale gas turbine model combustor

Methane and hydrogen-enriched (25 vol% and 50 vol% H2-enriched CH4) methane/air premixed flames were investigated in a gas turbine model combustor under atmospheric conditions. The flame operability ranges were mapped at different Reynold numbers (Re), showing the dependence on Re and H2 concentrations. The effects of equivalence ratio (Φ), Re, and H2 enrichment on flame structure were examined em

Learning control for flex-fuel CI engine and fuel cell

This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.The flex-fuel engine gas system models describ

Investigation on the pressurized discharge performance from a liquid oxygen tank under different injected gas temperatures

Accurate prediction on the pressurized discharge performance is significant to the safety operation of cryogenic propellant system. In the present study, a two-dimensional numerical model is established to simulate the fuel outflow with high-temperature gas injection. Both the environmental heat invasion and interfacial phase change are detailedly considered. The volume of fluid method is used to

An analysis of ammonia synthesis by the model of Selective Energy Transfer (SET)

The SET theory implies that energy is transferred from the catalyst system via infrared radiation to the molecules that are supposed to react. In previous investigations it has been demonstrated that the activation of the reacting species-as long as the molecules are infrared active-can occur at low adsorption strength. However, for molecules that are IR inactive, e.g. dinitrogen, this is not poss

A Multi-Zone Model for Hydrogen Accumulation and ventilation in Enclosures

Due to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons. This, together with the high reactivity, makes an efficient ventilation system very important in hydrogen applications. There are several models available for ventilation sizing that are based on either a well-mixed assumption or a fully stratifDue to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons.

Advancements in Laser-Induced Lifetime Measurements for Combustion and Plasma Studies

De senaste teknologiska framstegen har lett till skapandet av högspecialiserade system inom olika industrier, vilket möjliggör uppgifter som tidigare varit otänkbara. I takt med att den globala efterfrågan på hållbara och effektiva energilösningar ökar, har behovet av innovation inom teknik aldrig varit större. Dessa framsteg representerar transformativa förändringar som omformar hela sektorer. FrRecent technological advancements have led to the creation of highly specialized systems across various industries, enabling tasks that were once beyond imagination. As the global demand for sustainable and efficient energy solutions grows, the urgency for innovation in technology has never been greater. These advancements are not simply incremental but represent transformative changes that are re

Folding thermodynamics of three beta-sheet peptides: A model study

We study the folding thermodynamics of a beta-hairpin and two three-stranded beta-sheet peptides using a simplified sequence-based all-atom model, in which folding is driven mainly by backbone hydrogen bonding and effective hydrophobic attraction. The native populations obtained for these three sequences are in good. agreement with experimental data. We also show that the apparent native populatio

Business Case, Design and Simulation of Solar Powered Hydrogen Refuelling Stations

Abstract The thesis investigates some possible pathways for how solar powered Hydrogen Refuelling Stations (Solar-HRS) can be implemented in a economically viable way. This is done by the use of a custom simulation model in MATLAB/Simulunk to simulate and evaluate the inner workings of the Solar-HRS. Two cases for Solar-HRS is looked at, one "on-grid" and one "off-grid". The po
