  1. 1. Role of damping in NVH CAE procedures

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Rahul Sharma; [2021]
    Nyckelord :NVH; CAE; Damping;

    Sammanfattning :   Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. LÄS MER

  2. 2. Optimization of sprue design for advanced investment casting through FEA analysis

    M1-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Kanthee Prathan; [2020]
    Nyckelord :Design; FEM; FEA; Investment casting; Sprue design;

    Sammanfattning : Investment casting is a complex manufacturing method with many challenges that must be solved before components of the right quality can be produced. TPC is a company that utilizes investment casting to produce a variety of products, lately the company has higher ambition in wanting to cast higher technical demanding component like heat resistant gas turbine blades.

  3. 3. Analysis of wall-mounted hot-wire probes

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik; KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Alvisi Alex; Perez Adalberto; [2020]
    Nyckelord :Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

    Sammanfattning : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

  4. 4. 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. 5. Fuktsäkerhet i ventilerade parallelltak

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Byggnadsfysik

    Författare :Gabriel Odén; Gustav Månhardt; [2020]
    Nyckelord :Parallelltak; WUFI; blinda beräkningar; varierad luftomsättning; luftflödesmodell; fuktsäkerhet; MRD; termisk drivkraft; klimatdata; ventilerad luftspalt; värme och fukttransport; konvektion; analytisk lösning; fallstudie; Technology and Engineering;

    Sammanfattning : Parallel roofs are commonly used in Sweden when constructing new small house buildings and are also difficult to access for inspection. Furthermore, high demands are set in the Swedish building regulations, although there are no clear guidelines for their compliance. LÄS MER
