  1. 1. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

    Abstract : To develop anaerobic digestion (AD), innovative solutions to increase methane yields in existing AD processes are needed. In particular, the adoption of low energy pre-treatments to enhance biomass biodegradability is needed to provide efficient digestion processes increasing profitability. READ MORE

  4. 3. Hydrodynamic cavitation applied to food waste anaerobic digestion

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : David Tran; [2016]
    Keywords : Anaerobic Digestion; Biogas; Pre-treatment; Hydrodynamic cavitation;

    Abstract : Innovative pre-treatment methods applied to anaerobic digestion (AD) have developed to enhance the methane yields of food waste. This study investigates hydrodynamic cavitation, which induce disintegration of biomass through microbubble formations, impact on food waste solubilisation and methane production during following AD.

  5. 4. Hydrodynamic cavitation applied to anaerobic degradation of fats, oils and greases (FOGs)

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Johan Lunnbäck; [2016]
    Keywords : FOG; Hydrodynamic cavitation; Anaerobic digestion; Pre-treatment; Oil emulsion;

    Abstract : To increase profitability for biogas production, new innovative substrates and condition of operations needs to be implemented. At the current state, fats, oils and greases (FOGs) represent a promising substrate even though it brings operational challenges to the anaerobic digestion process. READ MORE
