  1. 1. Numerical study of a jet impacting a heated object

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Moutaz Hammoud; [2023]
    Keywords : Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Abstract : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. READ MORE

  3. 2. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE

  4. 3. 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.

  5. 4. Numerical heat transfer studies and test rig preparation on a gas turbine nozzle guide vane

    University essay from KTH/Kraft- och värmeteknologi

    Author : Khashayar Khorsand; [2014]
    Keywords : Boundary layer; Gas turbine blade; numerical methods;

    Abstract : Heat transfer study on gas turbine blades is very important due to the resultant increase in cycle thermal efficiency. This study is focused on the heat transfer effects on a reference nozzle guide vane and test rig component preparation in heat and power technology division at KTH. READ MORE

  6. 5. Influence of In-vessel Pressure and Corium Melt Properties on Global Vessel Wall Failure of Nordic-type BWRs

    University essay from KTH/Kärnkraftssäkerhet

    Author : Andrei Goronovski; [2013]
    Keywords : Severe accident; Vessel failure; CRGT cooling; Thermo-Mechanical creep analysis;

    Abstract : The goal of the present study is to investigate the effect of different scenarios of core degradation in a Nordic-type BWR (boiling water reactor) on the reactor pressure vessel failure mode and timing. Specifically we consider the effects of (i) in-vessel pressure, (ii) melt properties. READ MORE
