    Master Thesis
    Turbulence measurements in the wall jet layer of impinging round jet
    (Izmir Institute of Technology, 2012) Malak, Serdar; Özkol, Ünver
    The objective of this thesis is to understand how turbulence affects the impinging jet flow and heat transfer mechanism under acoustic actuaion. This work is based upon the experimental work including velocity and turbulence measurements in various cases and is a continuation of studies of Necati Bilgin and Orcun Kor . Acoustic actuation is provided by a loudspeaker controlled by a function generator. Acoustic waves generated by the loudspeaker reaches nozzle and formed periodic fluctuations in flow. Strouhal number, which is dimensionless reperentation of actuation frequeny, is varied in the range of 0
