  1. 1. Fouling modelling in a UHT unit based on plant data.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Thai Lam; [2023]
    Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE

  3. 2. Comparative Analysis of Modern Energy Systems for Ice Rinks

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

    Author : Pendar Hemati; [2023]
    Keywords : Ice rinks; refrigeration; heat recovery; CO2; ammonia; propane; Pistas de hielo; refrigeración; recuperación de calor; CO2; amoníaco; propano;

    Abstract : Ice rinks are highly energy-intensive commercial buildings with an average annual energy consumption of 1,000 MWh, most of it being used to cover the simultaneous heating and cooling demands. The aim of this thesis is to find the most energy efficient energy system for ice rinks by evaluating different system modifications and refrigerants. READ MORE

  4. 3. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Musole Kambita; [2022]
    Keywords : Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Abstract : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. READ MORE

  5. 4. CFD Analysis of the Flow Into a Preheater

    University essay from KTH/Teknisk mekanik

    Author : Eric Axtelius; [2022]
    Keywords : Mechanics; Fluid Mechanics; CFD; Preheater; Moisture Separator; Nuclear; Steam; Heat Transfer;

    Abstract : This project has investigated and formed a basis for the thermal- and flow-induceddynamic loads in the lower parts of a preheater situated in a nuclear power plant.Special attention has been given to the bottom plate that separates the heated andnon-heated secondary steam. READ MORE

  6. 5. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
    Keywords : CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

    Abstract : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. READ MORE
