Abstract
The gust wind tunnel at IDR, Universidad Politécnica de Madrid (UPM), has
been enhanced and the impact of the modification has been characterized.
Several flow quality configurations have been tested. The problems in measuring
gusty winds with Pitot tubes have been considered. Experimental results have
been obtained and compared with theoretically calculated results (based on
potential flow theory). A theoretical correction term has been proposed for
unsteady flow measurements obtained with Pitot tubes. The effect of unsteady
flow on structures and laying bodies on the ground has been also considered. A
theoretical model has been proposed for a semi-circular cylinder and
experimental tests have been performed to study the unsteady flow effects,
which can help in clarifying the phenomenon.
Keywords: hot wire anemometer, gust wind flow, Pitot tube measurements, gust
wind tunnel correction factor for Pitot tubes, unsteady flow measurements,
ballast pickup, influence of gusty winds, gust characterization, unsteady flow’s
effects on structures.
