    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Elias Bäckman; Mathilda Willén; [2019]
    Keywords : Decompression; Hydrogen gas; Tesla valve; no-moving parts; CFD; valve-to-valve; 压降;氢气;特斯拉阀;无可动阀芯;计算流体动力学;级间距; Decompression; Hydrogen gas; Tesla valve; No-moving parts; CFD; valve-to-valve;

    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE

  2. 2. Cooling Potential of Methane in Rocket Nozzle Cooling Channels : A Conjugate Heat Transfer Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marcus Pettersson; [2019]
    Keywords : ;

    Abstract : The use of hydrocarbons as fuel in rocket propulsion has been of great interest to the aerospace industry in recent years. Specifically, natural gas with a high content of methane has taken the interest of several actors, among them Sweden-based GKN Aerospace who in collaboration with KTH Royal Institute of Technology have started the MERiT project.

  3. 3. Fire Safety of Facades

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Keywords : polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Abstract : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. READ MORE

  4. 4. Experimental validation of a periodic heat transfer CFD model of a vertical shell and tube heat exchanger

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Bengtsson; Dilip Kumar Vellore Saikumar; [2019]
    Keywords : ;

    Abstract : Flow obstructions are used as a passive design element in heat exchangers to enhance heattransfer. Further, a change in flow structure can also have a positive effect on the heat transfer. Avertical shell and tube heat exchanger, used to recover heat in the greywater stream, isinvestigated in this study. READ MORE

  5. 5. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : Micaela Hamberg; Signe Dahlin; [2019]
    Keywords : VOF; RANS; Navier-Stokes; Spillway; Discharge tunnel; ANSYS; Fluent; CFD; Grid convergence index; Design of spillway; Cavitation; Gambit; k-epsilon; Ansys Gambit;

    Abstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE
