  1. 1. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Cyrus Ourak Pour; [2023]
    Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

    Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

  3. 2. CFD study of the different inlet configurations and airflows in a room with IJV

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Christos Stiapis; [2022]
    Keywords : Ventilation; CFD; Impinging Jet Ventilation;

    Abstract : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. READ MORE

  4. 3. Evaluation of drag estimation methods for ship hulls

    University essay from KTH/Mekanik

    Author : Hampus Tober; [2020]
    Keywords : ;

    Abstract : This study aims to evaluate to which degree CFD can complement traditional towing-tank experiments, and to develop a computationally cheap and robust methodology for these type of simulations. Two radically different surface ship hulls were chosen for the trials: a capesize bulk carrier and a fast displacement hull. READ MORE

  5. 4. Ventilation efficiency measurements - a comparison between three supply air methods

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Max Henriksson; Henrik Nilsson; [2016]
    Keywords : Ventilation efficiency; air exchange efficiency; local ventilation index; mean age of air; comparison; mixed ventilation; displacement ventilation; Technology and Engineering;

    Abstract : This study compares the two traditional ventilation methods ; mixed ventilation and displacement ventilation, with a new type of dif fuser which attempts to solve the problem with blockage of the diffuser for the displacement ventilation. This new diffuser called Airshower is a product developed by Airson engineering AB whom is also the company where all simulations and tests for this study were performed in a built office space.

  6. 5. Real-time simulation of diaphragm displacement during physiological and mechanical ventilation

    University essay from Avdelningen för beräkningsvetenskap

    Author : Linus Nilsson; [2013]
    Keywords : real-time; simulation; mass-spring; diaphragm; ventilation; respiration; surgery; simulation; deformation; soft-tissue;

    Abstract : This thesis presents a tunable 3D real-time interactive simulator of the geometrical displacement of the thoracic diaphragm during physiological and mechanical ventilation. Particular attention is placed on capturing the heterogeneous tissue composition while maintaining computational efficiency and accuracy. READ MORE
