CFD Simulation of Gas-Solid Two-Phase Flow in Pneumatic Conveying of Cathode Active Material

Batteriet uppfans för över 200 år sen men det är under det senaste deceniet vi har åskådat en storskalig utökning av dess tillverkning, i takt med den globala elektrifieringen. Efterfrågan på batterier förväntas öka med 22-30% årligen till 2030 vilket sätter stor press på industrin att utöka produktionskapaciteten. Men stora faror kan uppstå om tillverkningsprocesserna designas med bristande kvaliThis master thesis explores the mechanisms and optimization strategies of a pneumatic conveying system. By investigating the impact of process parameters on power consumption and erosion rate, the aim was to provide valuable insights for system design and operation. The research combines theoretical considerations, CFD simulations, and numerical calculations to analyse the behaviour of the system

Effects of recirculating water treatment sludge

Kan slam från vattenrening återanvändas hos vattenverken för en mer hållbar dricksvattenproduktion? I takt med att befolkningen ökar, ökar även behovet av dricksvatten. Hur ska man möta det här behovet på ett hållbart sätt? Jo, genom att återanvända slam – en restprodukt från dricksvattenproduktionen. I Sverige används både ytvatten från sjöar och grundvatten för att tillgodose befolkningens be-Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g., decreasing the amount of chemicals in the process. When producing drinking water, coagulation and flocculation are common processes. Briefly, coagulation is the process when negatively charged organic matter is destabili

Evaluation and merging of multiple gridded surface soil moisture products in Europe using ICOS measurements and triple collocation analysis

Mängden vatten i markens ytskikt, markfuktigheten, är viktig för ekosystem, jordbruk samt vattnets- och kolets kretslopp. Markfuktighet är även en indikator för torka och eftersom extremt väder ökar på grund av de globala klimatförändringarna läggs allt mer resurser på dess övervakning. Övervakning av markfuktighet görs vanligen antingen via punktbaserad mätning direkt i marken eller via satellitSurface soil moisture (SM) is an essential climate variable that plays a key role in ecosystems and the energy, water, and carbon cycles. SM can be accurately measured using in situ measurements. However, these measurements are globally not densely located over large areas, which would be required for accurate large-scale SM estimation due to the high spatial variability of SM. Instead, global atm

Rise of the Rwandan economy post-genocide: will this lead to catch-up growth?

Abstract: This thesis examines the concept of sustainable economic growth in post-genocide Rwanda, focusing on its structural transformation from the agricultural sector towards the service sector. This exploration essentially regards the implications for catch-up growth in light of the new notion of premature deindustrialisation. The role of Human Capital and Information and Communication technol

Finance for the Future– the Effectiveness of Voluntary Net-Zero Alliances for Financial Institution

Scaling up climate finance is vital for avoiding the worst impacts of climate change and limiting global warming. In this light, multiple Voluntary Net-Zero Alliances for Financial Institutions (VNZAFIs) have been founded, directing capital flows from financial institutions towards climate action. Nonetheless, the contributions of VNZAFIs to the Paris Climate Goals can be put into question. This s

EMU och internationell handel. Fördel eller ett sänke?

Some say that if Sweden join the Euro, it will increase the welfare in the economy. On the other hand, there are those who are skeptical toward Sweden joining the Euro, because it might risk the control over the currency to dropped and for the competitiveness to be lost. The international trade is large and important facto to increase the GNP growth. That is why this paper tend to examine to what

Ageing Populations and World Trade: Blight or Blessing?

Since the last half of the twentieth century, population ageing has increasingly become a problem for countries all over the world. The literature on population ageing is very well- established, however, it is lacking in one significant respect. That is, hardly any research has been done on how population ageing may affect international trade. Therefore, this thesis seeks to establish this effect.

Batteries, green energy transition and energy security in the EU: a critical analysis of REPowerEU

Batteries and renewable energy sources are key to the green energy transition and decarbonization. The EU has plans for green energy transitions and to mitigate climate change, but it is still largely dependent on imported fossil fuels. China dominates resources, materials and technologies for green energy transitions. With the recent energy crisis and Russian invasion of Ukraine, energy security

The evolution of lexical semantics dynamics, directionality, and drift

Introduction: The directionality of semantic change is problematic in traditional comparative models of language reconstruction. Compared to, e.g., phonological and morphological change, the directions of meaning change over time are potentially endless and difficult to reconstruct. The current paper attempts to reconstruct the mechanisms of lexical meaning change by a quantitative model. We use a

Monitoring deforestation in the Serranía de Chiribiquete in northern Colombian Amazon using time series analysis of satellite data

Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring. However, there are few stu

INVESTIGATING THE EFFECTS OF PROMOAT BETAGLUCAN ON IMPROVING AND MAINTAINING THE DESIRED STRUCTURE AND PHYSICAL PROPERTIES OF SPONGE CAKES OVER TWO WEEKS OF STORAGE.

This project investigated the impact of beta-glucan on sponge cake's desired texture and physical properties. Sponge cakes with different percentages of Lantmännens PromOat beta-glucan (0.0%, 1.0% and 2.0%) were produced and compared on the following parameters: volume, density, water activity, moisture content and texture profile analyses. These parameters were measured on different storage d

Characterization of immune niches in non-small cell lung cancer

Lung cancer, particularly non-small cell lung cancer (NSCLC), is a leading cause of cancer-related deaths globally. Immunotherapy using immune checkpoint inhibitors (ICI) is a potent treatment for NSCLC; however, long-term response is limited in the majority of patients and there is a lack of predictive biomarkers. Tertiary lymphoid structures (TLS) may serve as biomarkers for predicting ICI respo

Changing multinational organizations: Factors affecting organizational change

Multinational organizations operating in a changing business environment endure recurring reorganizational efforts. The process of changing a multinational organization is an ambiguous and complex activity. To achieve the desired outcome from an organizational change, factors affecting the change are highly relevant to regard and act upon. This thesis aims to identify and to understand what facto

The Future of Urban Last Mile Deliveries - Not a piece of cake

Urban last mile delivery has become an increasingly relevant topic in this day and age, where the urban population is growing at the same time as climate change forces nations to limit emissions. The demand for fast and flexible deliveries in urban areas accelerates, which further escalates the need to optimize these last mile deliveries since they are the most polluting part of the supply chain.
