Referat Syntetiska virvlar som inflödesvillkor för Large Eddy - simulering Large Eddy - Simuleringar (LES) blir allt vanligare som ersättare för Reynolds-Averaged Navier-Stokes beräkningar för extern och intern aerodynamik. LES-modeller behöver ett turbulent inflöde. I detta arbete studeras Synthetic Eddymetoden, som med stokastisk metod genererar ögonblickliga hastighetsfält. Metoden har implementerats i en industriell strömningslösare (elsA) och validerats på fall med homogen isotrop turbulens och utvidgats till kanalströmning. SEM jämförs med andra metoder som periodisk LES som "återanvänderden strömning som lämnar området.
Acknowledgments Firstly I would want to thank my supervisor at CERFACS Jean-François Boussuge who followed carefully the progression and quality of the work through a defined schedule and was always available for any assistance. Moreover I wanted to express my grateful to Hugues Deniau, Marc Montagnac and Guillaume Puigt for their regular support regarding the implementation inside the elsA code or technical problems. Then I appreciated the work atmosphere at CERFACS, namely, very professional and international through many seminars, as well as very convivial and friendly. Finally I thank my professors from KTH, Michael Hanke and my supervisor, Jesper Oppelstrup, as well as Ulrich Rüde, from the University of Erlangen, to have allowed me to realize my master’s thesis abroad during the double degree program, being always motivating and available for any advice.
