Description

The Scientific and Technical Centre for Building (CSTB) has been operating the Jules Verne Climatic Wind Tunnel (JVCWT) in Nantes since 1990. This facility includes two wind tunnels with climatic control from -30 to +50°C, with wind velocity up to 140 km/h or 280 km/h). This large facility allows simulating severe climatic conditions either cold or warm combined all kind of precipitation.

The facility is made of two separate circuits, with the focus in this case on the external dynamic circuit (JVCWT 1), which enables the reproduction of the spatial and temporal evolution of natural wind up to an average of 100 km/h in the environmental test section. This can be associated with rain (up to 250 mm/h). The highest air speed of 280 km/h is reached in the 30 m² High Speed test section. This section includes a six-component balance associated with a turntable and a boundary layer trap.

The main technical characteristics of the Jules Verne facility are the following:

  • Cross surface of aero. test section SC1: 30m²
  • Max wind velocity aero. section SC1: 280km/h
  • Cross surface of atmo. test section SC1: 100m²

It is expected that a typical experimental programme lasts five days. Hence, the actual experimental work will be planned 4 to 6 months in advance. The regular work schedule of the facility is usually planned at least 3 months in advance. The early scheduling of the experimental period of users under this project will avoid the risk. Before the experimental period, a preliminary meeting is organised at the facility to discuss both the practical research programme schedules and the technical requirements to achieve the goals of the users. All necessary equipment and human resources of the facility are pre-booked during this meeting to alleviate the risks of unavailability due to other project implementation. The preparatory meeting is part of the project.
