  • Experimental Study of sound propagation in a street
    Applied Acoustics, 2005
    Co-Authors: Judicaël Picaut, T. Le Pollès, P. L’hermite, V. Gary
    Abstract:

    This paper presents an Experimental Study of the sound propagation in a street, performed during July 2002, in order to measure impulse responses at numerous locations in a street canyon, and, for several positions of the sound source. A specific attention has been paid on the processing of the Experimental data, in order to obtain accurate values of the reverberation time and the steady-state sound pressure level, including also the compensation of the atmospheric attenuation. In total, 11 592 useful data have been collected during this experiment, and are available by contacting the corresponding author. Reverberation times and sound levels, in the narrow street, are then analyzed and compared, for the 4 source positions in the street. This Experimental Study gives interesting results on the behavior of the sound field in the street.

  • Experimental Study of transient boiling
    2013
    Co-Authors: Roberta Visentini, Pierre Ruyer, Catherine Colin
    Abstract:

    The clad to coolant heat transfer is a key issue in the safety evaluation of the clad failure risk during a reactivity initiated accident (RIA). It has been demonstrated that under very fast transient conditions such as those of RIA, the steady state correlations are not valid. Dedicated experiments simulating RIA conditions are required to determine the transient transfers and deeper understanding of the transient boiling phenomena is desirable. This paper presents an Experimental Study of the onset and development of boiling of a refrigerant flowing over a half-cylindrical wall whose heating rate is mastered. Thanks to the design of the facility, synchronized wall temperature measurement and flow visualization allow to characterize and analyse the heat transfer for the different boiling regimes. From the main results of the first tests campaigns, the impact of the wall heating rate on the boiling curve is discussed. We then draw some perspectives for further campaigns and analysis.
