The present aim is to reveal the flow past a pipe which is immersed parallel to the mainstream at high Reynolds numbers. In a wind tunnel, we carry out (1) base-pressure measurements, (2) velocity-fluctuation measurements using a hot-wire anemometer and (3) flow visualisations by a smoke-wire method with PIV analyses, where we take consecutive picu...

... And, such researches have been still less active than a sphere or a disc, although they are useful in many industrial fields such as the designs Hirata, Kida, Nakai, Miyahara, Naito, Tanigawa and Nakano, Journal of Fluid Science and Technology, Vol.13, No.3 (2018) for combustors, ventilator nacelles, screw casings, streamers and flowmeters as well as flying toys. While there have existed few researches on the flow past a pipe (Hirata et al., 2013), we can find several researches on the flow past a ring, a torus or a washer (Takamoto, 1987;Leweke et al., 1993;Hirata et al, 2001;Sheard et al., 2005;Hirata et al., 2006;Hirata et al., 2007). For renewable-energy applications, the flow has attracted our attention in the context of a new-concept windmill design (Ohya et al, 2006). ...
