Abstract

The flow over a finite-height cylinder of aspect ratio H:D=2:1 has been studied by means of oil-film visualization, pressure and heat flux fluctuation measurements. The measurements were concentrated on the diameter-based Reynolds number of R ed = 2 x 105. A novel heat flux gauge with a high spectral resolution was used to investigate the heat flux fluctuation on the surface of a slightly heated cylinder. Comparative investigations showed qualitative correlations between the pressure and heat flux fluctuations around the cylinder and on its free-end. Several flow features could be identified by means of time-resolved surface measurements.
