  1. 1. Drivers of sea level variability using neural networks

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Linn Carlstedt; [2023-05-10]
    Keywords : ;

    Abstract : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

  3. 2. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : David Ek; [2023-01-09]
    Keywords : ;

    Abstract : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. READ MORE

  4. 3. Trip redistribution and calibration of the mode choice model of Catalunya

    University essay from KTH/Transportplanering

    Author : Julien Rigaut; [2022]
    Keywords : ;

    Abstract : This paper investigates the creation and calibration of a mode choice model for Catalunya. Trip redistribution was performed as the data from light rail trips displayed the number of trips made between stations and not between the actual origin and destination of the trip maker. READ MORE

  5. 4. 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

  6. 5. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sergi Tarroc Gil; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE
