  1. 1. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

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

    Author : LINDA YANG; [2023]
    Keywords : Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

    Abstract : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. READ MORE

  3. 2. Solving Partial Differential Equations With Neural Networks

    University essay from Uppsala universitet/Matematiska institutionen

    Author : Håkan Karlsson Faronius; [2023]
    Keywords : Partial differential equations; neural networks; physics-informed neural networks; deep ritz method; fourier neural operator; importance sampling; inverse problems;

    Abstract : In this thesis three different approaches for solving partial differential equa-tions with neural networks will be explored; namely Physics-Informed NeuralNetworks, Fourier Neural Operators and the Deep Ritz method. Physics-Informed Neural Networks and the Deep Ritz Method are unsupervised machine learning methods, while the Fourier Neural Operator is a supervised method. READ MORE

  4. 3. A Heroine of Change and Consolidation : Elizabeth Bennet: A Harbinger of Change in Jane Austen’s Pride and Prejudice

    University essay from Mittuniversitetet/Institutionen för humaniora och samhällsvetenskap

    Author : Dianne Lesley Magtulis Cano; [2022]
    Keywords : marriage; wedding; tradition; change; wealth; money; female characters; women; love; patriarchal society; gender bias; 18th century; 19th century; feminism; feminist; heroine;

    Abstract : Pride and Prejudice has remained one of the most popular literary since it was published due to the concept of shifting social structure. Marriage is one of the most critiqued concepts by different scholars, giving their views on what would be the implication portrayed by Elizabeth Bennet and her influence on Mr. Darcy to marry for love.

  5. 4. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sandra Edström; [2022]
    Keywords : groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

    Abstract : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

  6. 5. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Soumen Ghosh; [2022]
    Keywords : Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Abstract : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. READ MORE
