1. 1. Method Development for Heat Transfer Predictions in Channel Flows : An efficient CFD approach for ribbed stationary channels

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Martin Leskovec; [2016]
   Nyckelord :CFD; roughened channels; heat transfer coefficient; HTC; Nu number; CAE process;

   Sammanfattning : Gas turbines are today used in numerous industrial and aeronautical applications. To increase the specific power output and efficiency, a high turbine inlet gas temperature is desired. The high temperature leads to the need of cooling critical components in the hot gas path.
