1. 1. Development of Elastic Mechanism for actuation of Valve

   University essay from KTH/Maskinkonstruktion

   Author : Nidhi Menon; [2023]
   Keywords : Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

   Abstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

3. 2. IMPLEMENTATION OF OXYFUEL COMBUSTION IN A WASTE INCINERATION CHP PLANT : A Techno-Economic Assessment

   University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Author : Mostafa Saleh; Anton Hedén Sandberg; [2021]
   Keywords : CCS; Oxyfuel Combustion; Carbon Capture; Gas Separation Techniques; Waste Combustion; Cost Assessment of CCS; ASU; CPU; Wet-FGR; Dry-FGR;

   Abstract : Global energy demand is predicted to rise in the coming decades, necessitating a shift to renewable energy sources to mitigate greenhouse gas emissions. However, due to the inability to supply renewable energy around the clock, it is estimated that only by adding an important technology, carbon capture and storage (CCS), it could be possible to reduce 80% of the 1990s greenhouse gas emissions.

4. 3. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Fabian Weber; [2019]
   Keywords : optical; analysis; hydrogen; h2; cooling; film; high; pressure; combustion; chambers; rocket; engine; thrust; experimental; oh*; shadowgraphy; flame; emission; lox; liquid; bipropellant; cryogenic; efficiency; heat; flux;

   Abstract : For performance optimisation of modern liquid cryogenic bipropellant rocket combustion chambers, one component which plays an important role in reducing the wall side heat flux, is the behaviour of the cooling film. At the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldshausen, hot test runs have been performed using the experimental combustion chamber BKM, to investigate the wall side heat flux which is -- among other factors -- dependent on cooling film properties.

5. 4. CHP process evaluation, optimization and troubleshooting in OpenModelica

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

   Author : HANNES WISTRAND; [2017]
   Keywords : ;

   Abstract : As an important part in creating a sustainable energy sector the most prevalent sources of energy production must be in the forefront of being both reliable and effective. In Sweden district heating is utilized in more than half of all households and must therefore be subject to the same scrutiny and analyses as other energy producing technologies. READ MORE

6. 5. MODELLING POLYGENERATION WITH DESICCANT COOLING SYSTEM FOR TROPICAL (AND SUB - TROPICAL) CLIMATES

   University essay from KTH/Energiteknik

   Author : Lekha Udayanganie Bakmeedeniya; [2011]
   Keywords : Polygeneration; Desiccant cooling; Humidity ratio; Coefficient of Performance;

   Abstract : Modelling Polygeneration with Desiccant Cooling System for Tropical(and Sub Tropical) ClimatesAbstractSpace cooling has become a necessity in tropical countries. Maintainingcomfortable indoor conditions in industrial environments incur high energy bills due toheavy dependency on electrically operated air conditioning systems. READ MORE
