  1. 21. Flow pattern analysis of a Surface Flow Constructed Wetland : Treating surface runoff and landfill leachate water from the Löt waste management site

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Max-Bernhard Alm; [2020]
    Keywords : Surface flow constructed wetland; flow pattern analysis; numerical model;

    Abstract : The waste management and recycling company, Söderhalls Renhållningsverk (SÖRAB) have constructed a surface flow wetland in order to treat surface runoff from the waste management site, Löt. The contaminated water passes several treatment steps until it reaches the wetland and a subsequent soil infiltration step. READ MORE

  3. 22. CFD Study of Different Aircraft Cabin Ventilation Systems on Thermal Comfort and Airborne Contaminant Transport : A Study on Passenger Thermal Comfort and Indoor Cabin Air Quality.

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Logeshkumar Srinivasan Venkatesan; Abhishek Raina; [2020]
    Keywords : ;

    Abstract : Aircraft Cabin Ventilation systems are crucial for not only maintaining a fresh supply of air but also help in proper air distribution control and reducing airborne pathogen contamination. Passenger thermal comfort is of vital importance for a comfortable cabin environment and thus the need to measure environmental parameters such as velocity and temperature stratification for different ventilation systems is paramount.

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : David Bayat; Fabian Grönvik; [2020]
    Keywords : ;

    Abstract : Once a year an event is being held at the fluid physics lab at KTH. One of the main purposes of this event is to awaken an interest in the visiting students from other universities, by demonstrating fluid physics phenomena. Showing the transition from laminar to turbulent flow in an open water channel is one of the demonstrations. READ MORE

  5. 24. Design and Analysis of Continuous Virus Inactivation Reactors in Biopharmaceutical Production

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hanna Danielsen; [2020]
    Keywords : Chemical engineering; Kemiteknik; Virus inactivation; Chromatography; Technology and Engineering;

    Abstract : The biopharmaceutical industry is replacing the current batch process with a continuous one and an essential step in the downstream process is the virus inactivation (VI). The challenge with a continuous VI reactor is to generate a narrow residence time distribution (RTD), while ensuring a precise incubation time. READ MORE

  6. 25. Evaluation of decentralized ventilation system with heat recovery

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö
