  • Efficient investigation on fully developed flow in a mildly curved 180° open-channel

    Turbulent flow in meandering open channels is one of the most complicated and unpredictable turbulent flows as the interaction of various forces, such as pressure gradient, centrifugal force, and wall shear stresses severely affect the flow pattern. In order to improve significance in engineering application, understanding the overall flow characteristic is the focus. This paper presents the ...

  • SoNoScout rides the trams

    Sound Quality and Vehicle Condition Research to evaluate sound signals inside trams has been undertaken using Brüel& Kjær binaural microphones, Time Data Recorder and PULSE data acquisition and analysis system. The tests were performed on a number of trams manufactured between 1908 and 2008, on normal town routes. Based on acoustical, spatial recordings, the initial quality ...
