  • An investigation of milk powder deposition on parallel fins

    Walmsley, Timothy Gordon; Walmsley, Michael R.W.; Atkins, Martin John; Neale, James R. (2012-09-23)
    One method to reduce the energy consumption of industrial milk spray dryers is to recover waste heat from the exhaust dryer air. A significant challenge associated with this opportunity is the air contains a small amount ...
  • Analysis of skim milk powder deposition on stainless steel tubes in cross-flow

    Walmsley, Timothy Gordon; Walmsley, Michael R.W.; Atkins, Martin John; Neale, James R. (Elsevier, 2015)
    Particulate fouling on the gas side of heat recovery equipment is a common industrial problem. The aim of this study is to characterize the deposition of skim milk powder on a single bare tube in cross-flow. A custom built ...
  • Application of P-graph techniques for efficient use of wood processing residues in biorefineries

    Atkins, Martin John; Walmsley, Timothy Gordon; Ong, Benjamin H.Y.; Walmsley, Michael R.W.; Neale, James R. (AIDIC, 2016)
    It is anticipated that demand for chemicals and fuel derived from sustainably grown bio-mass will increase over the coming decades. Forest and wood processing residues and waste are likely to become a significant feedstock ...
  • Appropriate placement of vapour recompression in ultra-low energy industrial milk evaporation systems using Pinch Analysis

    Walmsley, Timothy Gordon; Atkins, Martin John; Walmsley, Michael R.W.; Neale, James R. (Elsevier, 2016)
    This study focuses on applying Pinch Analysis to an industrial milk evaporator case study to quantify the potential energy savings. Modern milk evaporators are typically integrated using both mechanical and thermal vapour ...
  • Approximation of non-linear cost functions in p-graph structures

    Ong, Benjamin H.Y.; Walmsley, Timothy Gordon; Atkins, Martin John; Walmsley, Michael R.W.; Neale, James R. (AIDIC, 2016)
    P-graph employs combinatorial and optimisation algorithms to solve process network synthesis (PNS) problem. However, the P-graph framework requires linear cost functions when optimising PNS problems. As a result, a high ...

  • Unified Total Site Heat Integration: Targeting, Optimisation and Network Design

    Tarighaleslami, Amir Hossein (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, ...
  • Energy Investment and Emissions Planning for Electricity Generation in Myanmar

    Win, Phyu Phyu (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 ...
  • Carbon Dioxide Emissions Reduction in New Zealand Transport Sector

    Chand, Alvin Vikash (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 ...
  • Heat Integrated Milk Powder Production

    Walmsley, Timothy Gordon (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 ...
  • Ultrasonic Air Leak Detection: An Investigation to Improve Accuracy of Leak Rate Estimation

    Wolstencroft, Hamish Roger (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 ...
