  1. 1. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Aniruddh Mohan; [2022]
    Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

    Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE

  3. 2. CFD simulation of gas turbine ventilation and gas dilution

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Lokesh Sathyanarayana; [2022]
    Keywords : CFD; Gas dilution; Gas turbines; Ventilation;

    Abstract : Gas turbine engines are one of the primary sources of electricity currently in the world. The assembly consists of multiple subsystems all of which are placed within an acoustic enclosure. Dilution ventilation is a widely used and recommended means of protection against the risk of explosion within gas turbine acoustic enclosures. READ MORE

  4. 3. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Samuel Eriksson; [2022]
    Keywords : Mechanical ventilation; high frequency ventilation; patient circuit dynamics; parameter estimation; system identification; Mekanisk ventilation; högfrekvent ventilation; patientkretsens dynamik; parameterestimering; systemidentifiering;

    Abstract : Artificial breathing is vital when it comes to treatment of critically ill patients where the natural breathing mechanism is insufficient. With the help of mechanical ventilators, the natural breathing mechanism of the patient can be assisted or even exchanged with the artificial breathing from the machine. READ MORE

  5. 4. 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.

  6. 5. Luftfuktighet i häststall : en jämförelse mellan morgon- och dagskontroller

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Rebecca Kopsch; [2019]
    Keywords : relativ luftfuktighet; häst; häststall; djurskydd; djurskyddskontroller;

    Abstract : Det är länsstyrelsen som ansvarar för djurskyddskontrollerna i Sverige. En sådan kontroll i ett häststall sker oftast på dagen, vilket är då hästarna har gått ut till hagarna. Om den relativa luftfuktigheten mäts när hästarna har blivit utsläppta är det inte säkert att värdet är det samma som ifall hästarna stått kvar inne. READ MORE
