1. 21. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Jaka Perovšek; [2018]
   Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

   Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE

3. 22. Determination of fossil share in combustion of waste : Development of a novel method using NIR spectroscopy to predict the content of plastics in RDF-material

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

   Author : Christian Dahl; [2018]
   Keywords : NIR; Near infra-red; spectroscopy; chemometrics; waste material; fossil share;

   Abstract : Incineration of waste materials has become a common way to handle a worldwide increase of produced waste materials. The problem with waste as fuel is that the material is not homogeneous and include a mixture of fossils and renewables. READ MORE

4. 23. The Miller Cycle on Single-Cylinder and Serial Configurations of a Heavy-Duty Engine

   University essay from KTH/Förbränningsmotorteknik

   Author : Varun Venkataraman; [2018]
   Keywords : Two-stage turbocharging; modelling and simulation; GT-Power; performance; Miller cycle; heavy-duty diesel engine; Tvåstegs turboladdning; modellering och simulering; GT-Power; prestanda; Miller-cykel; lastbils dieselmotor;

   Abstract : I jämförelse med sina föregångare, har moderna lastbilsmotorer genomgått en betydandeutveckling och har utvecklats till effektiva kraftmaskiner med låga utsläpp genom införandet avavancerade avgasbehandlingssystem. Trots att de framsteg som gjorts under utvecklingen av lastbilsmotorer har varit betydande, så framhäver de framtida förväntningarna vad gällerprestanda, bränsleförbrukning och emissioner behovet av snabba samt storskaliga förbättringar av dessa parametrar för att förbränningsmotorn ska fortsätta att vara konkurrenskraftig och hållbar.

5. 24. Techno-economic analysis of the Local System Operator concept in a multi-dwelling unit in Sweden : A parametric sizing and optimization of a PV-battery system with EVs equipped with vehicle-to-home application

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Joel Mars Bodell; Camilo Tapia Chiriboga; [2018]
   Keywords : ;

   Abstract : The climate change of the environment raises concerns about the increasing greenhouse gas (GHG) emissions where the energy sector is a large contributor to the emission problems. As the electricity demand rises, due to increased population, urbanisation, and improved lifestyle, expanding the renewable generation can solve the problem of covering the increased electricity demand while decreasing the GHG emissions.

6. 25. Modeling the complex ejecta on 2017 September 6-9 with WSA-ENLIL+Cone and EUHFORIA

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Anita Linnéa Elisabeth Werner; [2018]
   Keywords : CME; space weather; forecast; prediction; WSA-ENLIL Cone; EUHFORIA; preconditioning; type II radio burst; kmTII; dcld; September 2017; geoeffective;

   Abstract : Three CMEs which erupted on 2017 Sep 4 and 6 underwent mutual interaction before reaching Earth on Sep 6-9, where it gave rise to a complex and unexpectedly geoeffective structure as detected by WIND at L1. The spacecraft first observed an interplanetary (IP) shock on Sep 6 followed by a turbulent sheath. READ MORE
