  1. 1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Fredrik Malmström; [2024]
    Keywords : ;

    Abstract : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  3. 2. Exploring the interactive effects of light intensity and pH on coral oxygen production

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Sara Wirdemark; [2023-08-07]
    Keywords : Ocean acidification; light intensity; photosynthesis;

    Abstract : The study aimed to explore the possible interaction between acidification and light intensity and the effects on corals' oxygen production. Interactions between temperature and pH have been thoroughly researched and proven to cause immense stress on the world’s reefs. READ MORE

  4. 3. Effects of Energy Performance Improving Measures on a 1990's Brick House in Southern Czech Republic : Computer Simulations using IDA-ICE

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Vaclav Panek; [2023]
    Keywords : Final energy demand; Primary energy demand; Energy performance; Refurbishment; Single-family house; Space heating;

    Abstract : The residential sector was responsible for 25% of the Final Energy Demand (FED) in the European Union in 2015. Countries in Central and Eastern Europe such as the Czech Republic are particularly concerned with ensuring security of supply at the lowest possible cost in recent years. READ MORE

  5. 4. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Tanmmay Rout; [2023]
    Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  6. 5. Relations between intracellular pH and gamma-aminobutyric acid levels in tea (Camellia sinensis) leaves, after two types of anaerobic treatment

    University essay from SLU/Dept. Of Plant Biology

    Author : Mingmin Tao; [2023]
    Keywords : tea leaves; intracellular pH; gamma-aminobutyric acid; glutamate; decarboxylase; fluorescent dye;

    Abstract : Tea (Camellia sinensis) is one of the three major non-alcoholic beverages in the world. In Gabaron tea, the levels of γ-aminobutyric acid (GABA) are more than 1.3 mg/g. In the human body, GABA lowers blood pressure and cholesterol levels. READ MORE
