An integrated site and device selection methodology for the ocean wave energy sector
(The University of Waikato, 2021)The ocean covers approximately 70 % of the earth’s surface and contains an immense source of renewable energy, in terms of ocean waves. However, this resource is unevenly distributed throughout the world, and so, therefore, ... -
Automated retrofit of heat exchanger networks
(The University of Waikato, 2020)In a large industrial processing plant, a significant amount of process heat is generated using fossil fuels, contributing to New Zealand’s overall greenhouse gas emissions. While New Zealand’s renewable energy sources ... -
Botswana electricity sector planning and CO₂ emissions reduction through solar PV in office buildings
(The University of Waikato, 2017)Coal is the most abundant energy resource in Botswana, with a total reserve of about 212 billion tones. Currently 600 MW of electricity is generated from coal and 160 MW is generated from imported diesel fuel. With rising ... -
Carbon Dioxide Emissions Reduction in New Zealand Transport Sector
(University of Waikato, 2016)Carbon dioxide reduction from New Zealand transport sector can be reduced to 1990 levels if a wide range of methods are adopted such as fuel mix, electrification of vehicles and rail, and cycling. A comprehensive analysis ... -
Energy Investment and Emissions Planning for Electricity Generation in Myanmar
(University of Waikato, 2016)Hydropower plays a critical role in supplying electricity generation in the developing nation of Myanmar. Over the next 15 years (2015 – 2030) with anticipated rapid social and economic development in Myanmar, the demand ... -
Experimental and Numerical Investigations of Skim Milk Powder Stickiness and Deposition Mechanisms
(University of Waikato, 2009)The particle gun method and Computational Fluid Dynamics (CFD) modelling was used to study stickiness and deposition mechanisms of skim milk powder in an impingement jet hitting a stainless steel plate. The particular focus ... -
Heat Integrated Milk Powder Production
(University of Waikato, 2014)Dairy processing is critical to New Zealand’s (NZ) economy producing NZ$13 billion in exports for 2012 while consuming 32 PJ of fossil fuels for process heat. Three quarters of NZ dairy exports are milk powders. This thesis ... -
Investigation of the heat transfer enhancement effects of nanofluids in process heating and cooling
(The University of Waikato, 2022)The global energy system faces a dual challenge; the need for more energy and less carbon emission. Out of the 50 billion tonnes of greenhouse gases emitted each year, 24.2 % comes from energy use in industries such as ... -
Pressure screening studies with wood pulp
(The University of Waikato, 2006)Pressure screening is used in paper making to separate components of a wood pulp slurry (water, wood fibre and solid contaminant material) and to concentrate the wood fibre. The complex solid-liquid and solid-solid mechanisms ... -
Ultrasonic Air Leak Detection: An Investigation to Improve Accuracy of Leak Rate Estimation
(The University of Waikato, 2008)A compressed air test rig was designed to develop new procedures and improve the reliability of results that are obtained when conducting a leak survey using an Ultrasonic leak detector such as the UE Systems Ultraprobe. A ... -
Unified Total Site Heat Integration: Targeting, Optimisation and Network Design
(The University of Waikato, 2018)Process industries in New Zealand use 214.3 PJ of process heat, of which approximately 65 % is fossil fuels. Despite increasing energy demands, depleting fossil fuel resources, and pressure to reduce Greenhouse Gas emissions, ...
