  7. 5. Combustion Bowl Heat Transfer Analysis in Diesel and PPC Engines

    Author : Helgi Fridriksson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Transfer; CFD; Internal Combustion Engine; Diesel; PPC;

    Abstract : This thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine.
