1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

   Author : Kaibin Wen; [2023]
   Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

   Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

3. 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)

   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

4. 3. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Casper Berg; [2022]
   Keywords : Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

   Abstract : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.

5. 4. Integrating Chemical Looping Gasification for Hydrogen Generation and CO2 Capture in Pulp Mills

   University essay from KTH/Energiprocesser

   Author : Matilda Pamér; [2022]
   Keywords : Carbon Capture and Storage; Bio-CCS; Chemical Looping Gasification; Pulp Mill; H2 generation; Process Analysis; Bio-CCS; CLG; Massabruk; H2 generering; Process Analys;

   Abstract : Utsläpp av CO2 till atmosfären bidrar till ökningen av globala temperaturer. Industrisektorn står för 20 % av utsläppen och utav dessa kommer 6 % från pappers- och massaindustrin. För att lyckas minska den globala temperaturhöjningen till under 1,5 °C hjälper det inte bara att minska utsläppen. Även negativa utsläpp måste genereras. READ MORE

6. 5. Evaluation of improved Airflow in TM-102/II-DC

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Claudia Kazemi; [2022]
   Keywords : Airflow systems for electronics; thermal management; telecommunication equipment; airflow resistance; cooling of electronics.; Luftflödessystem för elektronik; termisk hantering; telekommunikations applikationer; luftflödesmotstånd; kylning av elektronik;

   Abstract : Within the company Infinera, there is a need for an improved thermal design of an existing chassis product for use in telecommunications for distribution of services within the Edge & Metro network. To enable an optimized airflow design of the chassis, there is a need of analyzingdifferent simulation cases performed in FloTHERM. READ MORE
