  1. 1. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    University essay from KTH/Materialvetenskap

    Author : Gustaf Bjurstam; [2023]
    Keywords : Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Abstract : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. READ MORE

  3. 2. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
    Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

    Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

  4. 3. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

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

    Author : Hamidreza Rastan; [2019]
    Keywords : Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Abstract : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  5. 4. Evaluation of Strategies for the Integration of Building Information Modelling (BIM) with Simulation of Fires in Enclosures

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Silvia Parra Diettes; [2019]
    Keywords : Building Information Modelling; Simulation of Fires; Computational Fluid Dynamics; Fire Dynamics Simulator; Thermal properties; Industry Foundation Classes; Technology and Engineering;

    Abstract : Computational Fluid Dynamics (CFD) is the study of fluid flows for the analysis of phenomena by scenarios simulated in a computer-based environment. One of the most well-known CFD simulation packages in the fire safety field is Fire Dynamic Simulator (FDS). READ MORE

  6. 5. Residual Stresses Induced by Welding in High Performance Steel

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Rebecca Erlingsdotter Stridsman; Felicia Månsson; [2018]
    Keywords : Residual Stresses; High Performance Steel; Heat transfer; Abaqus; Welding;

    Abstract : Today, high performance steel as a construction material is treated as conventional steel in the European standards. Referring to the Eurocodes, the buckling curves for dimensioning of steel constructions only presents values up to steel grade S460, meaning that the full potential of high performance steel is not considered.
