  4. 23. A study on axially rotating pipe and swirling jet flows

    Författare :Luca Facciolo; Herik Alfredsson; Helge I. Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.

  5. 24. Modelling crack-induced ultrasonic scattering in a thick-walled pipe

    Författare :Jacob Rubenson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cylindrical pipes; Non-Destructive Testing; Crack; Ultrasonic waves; Hypersingular integral method;

    Sammanfattning : Ultrasonic testing is used in several industries where there are high demands on safety, e.g. nuclear power and aerospace industries. In the nuclear industry and elsewhere there are many pipes that need to be tested. LÄS MER

  7. 25. Pulsed Neutron Activation for Determination of Water Flow in Pipes

    Författare :Håkan Mattsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flowmeter; Pulsed Neutron Activation; CFD; Pipe flow; PNA;

    Sammanfattning : In a Pulsed Neutron Activation (PNA) flowmeter neutron induced activity is used to measure water flow in pipes. The water in the pipe is bombarded with neutron pulses which introduce activity into the pipe. The activity is then transported and mixed with the flow. LÄS MER
