  2. 2. An Experimental and numerical study of heat transfer and pressure drop on the bend surface of a U-duct

    Detta är en avhandling från Heat Transfer

    Författare :Tareq Salameh; Lunds universitet.; Lund University.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. LÄS MER
