  1. 1. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sergi Tarroc Gil; [2021]
    Nyckelord :Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

    Sammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER

  3. 2. The Influence of Cavity Widths and Lateral Ventilation Conditions on the Fire Behaviour within a Non-Combustible Ventilated Façade System

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Fogerty; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Present uncertainties in key ventilation parameters, characterising the fire performance of facades, has necessitated clarification in the foundational understanding of the Fire Science Body of Knowledge. A test program conducted in collaboration between Lunds Universitet and the Kingspan Group, studied the influence of cavity widths and lateral ventilation conditions on the fire behaviour within Intermediate-scale ventilated façades following the ISO 13785-1 standards.

  4. 3. Investigation of heat transfer and mass transfer parameters in a convection oven for model foods

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Chandana Mysore Somashekar; [2020]
    Nyckelord :Food engineering; Livsmedelsteknik; Technology and Engineering;

    Sammanfattning : Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model food.

  5. 4. Solcellers effektivitet vid integrerat eller applicerat montage

    Master-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :August Larsson; [2019]
    Nyckelord :BIPV; air cavity; naturally convection; BIPV; luftspalt; skorstenseffekten; naturlig konvektion;

    Sammanfattning : Sweden has a climate target to get a total renewable electricity production by 2040, in order to succeed with the goal, the proportion of solar energy needs to increase. Increased environmental awareness and increased profitability of solar cells have led to an increase. LÄS MER

  7. 5. Tungans muskelaktivitet vid stamning : En kvalitativ studie med elektromyografi

    Magister-uppsats, Uppsala universitet/Logopedi

    Författare :Therése Brösemyr; Jessica Karlsson; Gustav Nordgren; [2019]
    Nyckelord :stuttering; tongue; EMG; PeriAcryl; method; design; core behaviours; stuttering categories; muscle tension; stamning; tunga; EMG; PeriAcryl; metodutveckling; stamningssymptom; stamningskategorier; muskelspänning;

    Sammanfattning : Stuttering is a speech disorder which involves recurrent disruptions of the fluency of speech. Previous research has investigated movements of the tongue during stuttering, but this excludes answers regarding the underlying activity of the muscles. LÄS MER
