  1. 21. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

    Keywords : Beta glucan; oat bran; subcritical water extraction; viscosity; particle size;

    Abstract : An increasing number of people are suffering from lifestyle related diseases due to poor dietary habits. The recommendation of a fibre intake of 25-35g per day is not achieved by many. READ MORE

  5. 24. Numerical and experimental investigations of gas jet used in atomisation of metal powders

    University essay from KTH/Materialvetenskap

    Author : Arun Kamalasekaran; [2020]
    Keywords : ;

    Abstract : The environmental impact caused by the traditional production techniques has led to increased research in the field of alternative production techniques such as additive manufacturing. However, the environmental sustainability of the manufacturing techniques that produce and supply powders to the additive manufacturing process can be improved significantly. READ MORE

  6. 25. Steady ideal flows with vorticity in toroidal domains and periodic cylinders

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Gustav Jillbratt; [2020]
    Keywords : Partial differential equations; Euler equation; Vorticity; Fluid dynamics; Mathematics and Statistics;

    Abstract : In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. READ MORE
