Wind tunnel experiments of the flow past a hemisphere in a thin flat plate boundary layer were conducted over a range of Reynolds numbers, based on hemisphere diameter from 6.36 × 104 to 1.55 × 105. Mean and unsteady surface pressure measurements, in conjunction with surface flow visualisation, were used to characterise the flow over the hemisphere and nearwake region. A frequency analysis of the surface pressure at a Reynolds number of 1.25 × 105 indicated broadband spectral activity in the Strouhal number range 0.12 to 0.18.
