Wind Tunnel

Owning Organization:
Contact: MARUYAMA Takashi
Resource classification: Experience equipment, Facilities, etc
Research area  (1): Building construction/material
A wind tunnel with open-circuit configuration designed
specifically for wind engineering research was completed
at the Disaster Prevention Research Institute (DPRI),
Kyoto University in 1981.
The wind tunnel has a working section of 2.5 m wide, 2 m
high and 21 m long with the maximum wind speed of 25 m/s
provided by a 170 kw variable speed electric motor. The
wind tunnel has some special apparatus to simulate the
atmospheric boundary later. On the upstream floor of the
working section, various combinations of flow processing
devices can easily be installed. The ceiling of the
working section is movable vertically and independently
every one meter to adjust the static pressure to be
uniform along the tunnel. The working section is equipped
with a 4-component traversing system which allows the
remote control of positioning of sensing probes.
The special features of the tunnel are: 1) non-turbulent
wind in the upstream, 2) uniformity of the wind speed and
pressure, 3) feasibility of wind speed control and the
ceiling adjustment, 4) an attached automatic system for
measurements and 5) quietness around the tunnel, etc.
