Abstract
Every year millions of people visit the works of art placed in museums, which
aren’t the safest place to protect cultural heritages from air pollutants.
The use of air curtains may often represent a protection for the cultural
heritage without operating on the material of the objects, and without limiting the
perception of the work of art. The aim of this work consists of the
characterisation of this device, which is widely used in industry, but not yet
frequently adopted in the field of conservation of works of art. As a matter of
fact, the employment of air curtains to segregate pollutant diffusion near the
sources of fire prevention is actually more and more diffused in industry
buildings. Their success is due to the peculiarity to separate zones without fixed
barriers which would interfere with people and equipment. The application of air
flows in museums deals with the problem of separating visitors and objects in
order to protect the latter from pollutants.
When a decontamination treatment of the visitors is provided, by means of an
air curtain system that is able to remove most of the potentially dangerous
pollutants from people as they enter, an \“indirect protection method” is defined.
An ongoing research of the latter is presently studied in the Museum of the
Rocca di Vignola (Modena) to remove pollutants from visitors of the fresco
painted chapel.
In the present paper some CFD simulations performed with FLUENT are
compared with the experimental measures realized after the first utilization of the
air curtain outside the fresco chapel of \“Uguccione Contrari” in Vignola.
As a preliminary result it is possible to underline the good accordance
between simulation and experimental results so that it is possible to be confident
in using CFD simulation code as a design tool for dynamic barriers against
pollutants in cultural heritage.
