Passive damping mechanism of Herschel-Quincke tubes for pressure pulsations in piping systems
(2018-12-01)
The acoustic pressure pulsations in industrial piping systems can induce fluctuating loads on inline equipment which may cause fatigue failure and in severe cases, initiate a phenomenon known as acoustic resonance. Passive ...
Design and analysis of an active underbody aerodynamic device for tractor trailers
(2018-04-01)
At highway speeds, up to 65 % of the total energy used by large trucks is for overcoming aerodynamic drag. The underbody region of a tractor-trailer is responsible for up to 30 % of the aerodynamic drag on tractor-trailers, ...
Development and assessment of renewable energy based integrated systems for dimethyl ether production
(2018-12-01)
Dimethyl-ether (DME) is considered to be one of the most promising, renewable alternative fuels. This thesis studies, develops, analyzes and assesses the performance of three dimethyl-ether production integrated systems, ...
Influence of sinusoidal motion on Stirling engines
(2018-12-01)
Stirling engines have a high potential to produce renewable energy due to their ability to use a wide range of sustainable heat sources and their high theoretical efficiencies. They have not yet achieved widespread use and ...
Thermal management of the thermochemical Cu-Cl cycle linked with industrial processes for hydrogen production
(2018-04-01)
This thesis study develops, analyzes and evaluates three integrated systems using process heats available in industrial applications for hydrogen production via copper-chlorine (Cu-Cl) cycle. The first system consists of ...
Investigation of copper deposition on steel in molten copper chloride
(2018-01-01)
Hydrogen is considered as the most prominent candidate for clean energy generation. The Copper Chloride (Cu-Cl) cycle has been chosen as an effective cycle for production of hydrogen due to its comparatively lower operating ...
Development and investigation of alkaline electrolyte based direct ammonia fuel cells
(2018-01-01)
In the present thesis study, alkaline electrolyte based direct ammonia fuel cells are developed, and their performances are evaluated through various parameters and efficiencies, such as open circuit voltages, polarization ...
Development of an integrated inspection system for additive and subtractive hybrid manufacturing
(2018-01-01)
Using closed-loop inspection systems to modify coordinate metrology tasks for specific engineering applications has been a demanding research subject over the last decade. The objective of this thesis is to develop an ...
A directional preference ETX measure for the collection tree protocol in mobile sensor networks
(2018-01-01)
There has been a growing interest in Wireless Sensor Networks (WSN) that utilizes mobile nodes for various purposes. These mobile wireless sensor networks tend to suffer from constant link breakages mainly caused by connected ...
Development and investigation of an ammonia synthesis reactor
(2018-08-01)
Ammonia production has gained increasing attention in the last decade due to its importance as a feedstock and an energy carrier. In the present thesis study, two novel ammonia production systems are presented. The first ...
