  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. 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.

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Logeshkumar Srinivasan Venkatesan; Abhishek Raina; [2020]
    Nyckelord :;

    Sammanfattning : 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.

  4. 3. Design of a Test Equipment : Quality Control on Hydraulic Quick Couplings Used in the Excavation Industry

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Daniel Andersson; Robin Florbrant; [2020]
    Nyckelord :Industrial design engineering; mechanical engineering; product design; ergonomics; anthropometrics; machine safety; repetitive work; test equipment; hydraulic quick coupling and excavator.; Teknisk design; maskiningenjör; produktdesign; ergonomi; antropometri; maskinsäkerhet; repetativt arbete; testutrustning; hydraulisk snabbkoppling och grävmaskin.;

    Sammanfattning : Construction machines use quick couplers to rapidly change the attached tool. The gear lets the machine operator control the hooking and unhooking of the tool from inside of the cabin. This saves time and makes construction work much easier for the workers. LÄS MER

  5. 4. Upgradation of lifeboat

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Venkata Naga Saras Chandra Daliparti; Naveen Sai Surya Ayyappa Bellamkonda; Venkata Vamsi Krishna Kola; [2020]
    Nyckelord :Accidents; Lifeboats; Passenger cabin; Ships;

    Sammanfattning : In today’s rapid development in world and globalization, transportation had become an important aspect in life. People transport through means of air, water and land. This made drastic increase of transportation and as a result the pollution levels are increased and so does the deaths due to accidents. LÄS MER

  7. 5. Flow and Air Quality Modelling of a Car Cabin

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Oskar Jolérus; [2019]
    Nyckelord :CFD; PM2.5; Air quality; Multiphase; LPT;

    Sammanfattning : Adverse health effects attributable to both short- and long-term exposure to air pollution have turned the focus on different microenvironments. The interior of vehicles is of relevance as road traffic emissions and re-suspension of road dust are major sources of pollutants associated with adverse health effects. LÄS MER
