A comprehensive, three-dimensional model of a proton exchange membrane (PEM) fuel cell based on a steady state code has been developed. The model is validated and further be applied to investigate the effects of various porosity of the gas diffusion layer (GDL) below channel land areas, on thermal diffusivity, temperature distribution, oxygen diffusion coefficient, oxygen concentration, activation
Popular Abstract in Swedish I denna studie har de grundläggande aspekterna på mass- och värmetransport i membrantekniken pervaporation studerats. Speciell tonvikt har lagts vid pervaporations användbarhet i samband med aromämnesåtervinning. Masstransporten i pervaporation påverkas av ett yttre masstransport- motstånd kallat koncentrationpolarisation. Detta fenomen kan orsaka att fluxen av de seleIn this study, the fundamental mass and heat transfer properties of the membrane separation process called pervaporation were investigated. The suitability of pervaporation for aroma compound recovery was especially evaluated. The mass transfer in pervaporation is affected by an external mass transfer resistance in the liquid feed boundary layer, i.e. the concentration polarization phenomenon. Th
The activated sludge process is the main process in most urban wastewater treatment systems. It is considered complex in nature, and building its mathematical model in practice becomes difficult. A simple and easy way to build the simulation models for the system is needed. In this paper, a LabVIEW based simulator for the system is presented. LabVIEW offers a highly efficient, simple and flexible
Stickiness between materials can be a challening task when dealing with the complex interactions and processes related to packaging engineering. Part of the problem is that many factors like temperature, pressure, surface treatment as well as surface roughness all could play a part in contributing to the stickiness between materials. In this thesis a literature study has been done to map out poten
The aim with this project is to renew the traditional beehive into a modern and easy to use device. Many people who are interested in becoming beekeepers hesitate due to a number of problems. One is the amount of time that you need to spend working with your bees, it’s also costly to buy all the things that you need for keeping bees and harvesting the honey. You usually need a shed where you can s
Grooming är en systematisk process, som för det första kränker barn och för det andra möjliggör att barn kan utsättas för fysiska övergrepp. Barn blir lurade särskilt av gärningsmän då de inte har samma skyddsmekanismer och riskmedvetande som en vuxen person. Kommunikationsteknologins framväxt under 2000-talet har utökat möjligheterna för vuxna som vill ta kontakt med barn i sexuellt syfte. År 200Grooming is a systematic process, which firstly violates children, and secondly enables children to be subjected to physical forms of abuse. Children are deceived especially as they lack the same psychological safety mechanisms and risk awareness as that of an adult. The growth of communications technology during the 21st century has increased the possibilities for adults that seek contact with ch
Mozambique has benefited from very high economic growth the last decade and is a large receiver of foreign aid. In spite of these high growth rates and foreign aid the population living in absolute poverty is still extremely high. The reason for this is that the growth rates have been driven by capital intensive foreign owned megaprojects that do not provide many jobs for the Mozambicans. This s
År 2017 togs beslut i Sveriges riksdag att anta ett nytt klimatmål där Sverige år 2045 ska ha noll nettoutsläpp av växthusgaser för att därefter ha negativa växthusgasutsläpp. Utifrån detta mål ställer Trafikverket vidare krav på sin verksamhet och sina väg- och järnvägsprojekt. Trafikverkets mål är att infrastrukturen ska vara klimatneutral till år 2050 med delmål att minska växthusgasutsläppen mIn 2017 the Swedish Parliament implemented a new national goal for limiting climate change. The goal is to have zero net emissions of greenhouse gases by year 2045 which will ultimately lead to negative net emissions. Further, the Swedish Transport Administration adapted the goal of making Sweden’s infrastructure climate neutral by the year 2050, with the milestones of reducing the emissions from
