  1. 21. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE

  3. 22. Machine Learning for Early Prediction of Pneumothorax in the Intensive Care Unit

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Emma Malm; [2022]
    Keywords : machine learning; deep learning; pneumothorax; intensive care unit; onset prediction;

    Abstract : By taking advantage of the increasing amount of available electronic health data, applications of machine learning in the intensive care unit have the potential to improve medical diagnostics and risk stratification. This thesis proposes an approach for early onset prediction of pneumothorax with such technique, using time series data extracted from a clinical database. READ MORE

  4. 23. CFD Study of An Office Room Equipped with Corner Impinging Jet Ventilation

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Getiye Wodaje; [2022]
    Keywords : CFD in ventilaion; Thermal comfort; Impinging jet ventilation; thermally stratified flow; Corner impinging jet; Office air quality; Indoor environment; turbulent jet;

    Abstract : A CFD validation study was made using corner supplied impinging jet ventilation operating in cooling mode. The air distribution system has two equilateral triangle shaped inlets placed 80cm above the floor at the two that share a common wall. The supply air was introduced at 2.26m/s. READ MORE
