1. 1. Come Fly with Me (Sustainably) : Pathways to Sustainable General Aviation and Private Pilot Training

   University essay from Högskolan i Gävle/Miljövetenskap

   Author : Michael Stiebe; [2022]
   Keywords : General Aviation; Sustainable Aviation; Sustainable Development; Electric Aviation; Noise Pollution; Leaded Fuel; AVGAS 100LL; Tetraethyl Lead Phaseout; Pilot Training; Recreational Aviation; Switzerland;

   Abstract : Whereas commercial aviation is attempting to achieve the reduction of its substantial carbon footprint, general aviation’s (GA) climate change contribution is negligibly small, which is why the sector is facing other sustainability challenges mainly entailing the operation of dated technology and aircraft, increasing regulatory constraints, rising costs, noise emissions, and popular discontent, as well as remaining the last mobility sector in the world to still use leaded fuels. Throughout recent years, there have been remarkable sustainability trends in GA as well as heightened efforts to improve its emissions profile (noise, pollutants, CO2) and environmental reputation, for instance by the increased use of electric aircraft, especially for private pilot training.

3. 2. Preliminary experimental study on the affect of water of the hydrogen reduced hematite pellet

   University essay from KTH/Materialvetenskap

   Author : Henrik Welander; [2021]
   Keywords : ;

   Abstract : Global warming is one of the most important challenges that we are facing today. Since carbon dioxide (CO2) is by far our most common green house gas pollutant,  most large corporations need to reconsider how their production is performed to keep the global warming below 2 ◦C.

4. 3. Design of flow guiding parts through CFD topology optimisation

   University essay from KTH/Fordonsdynamik

   Author : Aby Narayamparambil; [2021]
   Keywords : Topology optimisation in CFD; Ansys Fluent; Tosca Fluid; Particle track; Backflow tolerance; Topologi optimering i CFD; Ansys Fluent; Tosca Fluid; Particle track; Återflödets tolerans;

   Abstract : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. READ MORE

5. 4. Temperature Based Estimation of the Time-Resolved Massflux of ICE Exhaust Gas Flow

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

   Author : Mayur Khedekar; [2021]
   Keywords : ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

   Abstract : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. READ MORE

6. 5. Liquid Natural Gas : A study of the environmental impact of LNG in comparison to diesel

   University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

   Author : Jonas Edfors; Robin Bremberg; [2021]
   Keywords : Methane; LNG; Engine; Marine; Mole; Methane Slip; Ship; CO2; CH4; Emission; IMO; Exhaust gas; Environment; Propulsion; Heavy Fuel Oil; Ultra Low Fuel Oil; Diesel; Marine Diesel Oil; ECA; SECA; NECA; IMO; g kWh; EEDI; LSFO; Metan; LNG; Motor; Mol; Skepp; Miljö; Miljövänligt; Tjockolja; Diesel; Marine Diesel; Avgas; CO2; CH4; ECA; SECA; NECA; IMO; g kWh; EEDI; LSFO;

   Abstract : Liquefied Natural Gases (LNG) has been an alternative fuel in the marine industry for several years, but lately, the amount of ships that have been powered by methane has increased a lot. Some of the reasons for this is because LNG does not contain any sulfur and releases less nitrogen oxides than traditional maritime fuels. READ MORE
