  2. 11. An Experimental and Numerical Study of Heat Transfer and Pressure Drop on the Bend Surface of a U-duct

    Author : Tareq Salameh; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  5. 13. Sampling and analysis of polynuclear aromatic hydrocarbons with special reference to automobile exhausts

    Author : Ulf Stenberg; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : A literature survey concerning the progress in sampling of polynu clear aromatic hydrocarbons, PAH, from automobile exhausts is pre seated. In this conjunction the included analytical methods are discussed, and some emphasis is put on injection technique and column performance. READ MORE

  6. 14. Development of Methods for Determination of Fat and Trace Constituents in Food, with Emphasis on Supercritical Fluid Extraction

    Author : Hans Berg; Centrum för analys och syntes; []
