1. Experiments and simulations of gas flow through a NiCd battery
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : This report describes the thesis work carried out regarding experiments and simulations of the gas flow through a NiCd battery. The objective of the work was to investigate how different geometries of the flip top vent on the battery and the level of porosity of the flame arresting disc impacted the amount of potassium carbonate created at the outlet of the vent.

2. 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)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

4. Analysis of the flow of secondary steam through a reheater using 3D CFD
University essay from KTH/MekanikAbstract : In this study 3D CFD was used to study the mass flow distribution in a reheater in a nuclear power plant. The aim was to see if 3D-modeling provide different results than traditionally used 1D-analysis. Models with detailed geometry were created for a section of the tube package in the reheater to obtain pressure drop coefficients. READ MORE

5. Development of Light Transmission Techniques for Quantification of CO2 Trapping in Porous Media
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Light transmission can be used to measure the amounts of certain constituents within a system by analyzing the amount of light they have absorbed. The aim of this study was to improve methods for light transmission measurements in two phase systems. READ MORE
