   Nyckelord :;

   Sammanfattning : Carrying around 80-90% of world volume of goods, the shipping industry has a considerable environmental impact. The International Maritime Organization (IMO) fixed a 50% greenhouse gases emission reduction target by 2050 with respect to 2008 levels. LÄS MER

4. 3. Experimental assessment of fluid hammer prediction algorithms

   Kandidat-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

   Författare :Jessica Kihlström; [2018]
   Nyckelord :;

   Sammanfattning : Fluid hammer is a problem, which may lead to catastrophic consequences and many engineers have a deficiency in competence when it comes to its prediction. This study´s objective is to assess various fluid hammer prediction models, to evaluate how substantial pressure thrusts would affect a system and to verify the analytical results toward experimental data.

5. 4. A High Heat Flux Facility Design forTesting of Methane in Rocket NozzleCooling Channels

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Richard Ristic; [2017]
   Nyckelord :;

   Sammanfattning : Liquid natural gas, with a high content of methane, is one of the most prominent future solutions for rocket propellants. This is due to its efficiency in terms of specific thrust, in combination with several operational benefits including availability, storage stability and low toxicity. LÄS MER
