1. 21. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

   University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
   Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

   Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

3. 22. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Olivia Johansson; [2023]
   Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

   Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE

   Abstract : Sharing commodities such as vehicles and houses in exchange for a fee has become very popular in the recent years. Companies such as Uber and Airbnb are two examples where their users can rent their underutilized assets for a period of time. READ MORE

5. 24. Numerical simulations oflovastatin crystallization in aT-shaped 2D mixer

   University essay from KTH/Optimeringslära och systemteori

   Author : Anton Bergman; [2023]
   Keywords : ;

   Abstract : The rise of battery driven technology and the strive towards circular economy calls for the indefinite recycling of metals used in batteries. To be able to study and optimize the processes used in recycling, mathematical models are required. READ MORE

6. 25. Recycling end-of-life silicon PV panel with molten salt bath

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

   Author : Liying Yu; [2023]
   Keywords : ;

   Abstract : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. READ MORE
