1. 16. Compressor CFD simulation method development : A CFD study

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Johan Björk; [2018]
   Keywords : CFD; centrifugal compressor; CFX; CHT; Conjugate Heat Transfer; Surge;

   Abstract : This master thesis project consisted of three parts that all were performed through CFD simulations with the purpose to develop Scania's methods in the subject of CFD. All parts included simulations on Scania's SC92T70 centrifugal compressor. READ MORE

3. 17. A High Heat Flux Facility Design forTesting of Methane in Rocket NozzleCooling Channels

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

   Author : Richard Ristic; [2017]
   Keywords : ;

   Abstract : 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. READ MORE

4. 18. Pressure loss characterization for cooling and secondary air system components in gas turbines

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Frida Isaksson; [2017]
   Keywords : Gas turbines; cooling and secondary air system; pressure losses; discharge coefficient; minor loss; one-dimensional modelling;

   Abstract : There is a constant struggle to increase the efficiency in gas turbines, where one method is to have a higher inlet temperature to the turbine. Often, this results in temperatures higher than the critical temperature of the materials, which makes cooling of the components an important part of the turbine. READ MORE
