Résumé

Airflow characteristics in ventilated and air-conditioned spaces play an important role to attain comfort and hygiene conditions. This paper utilizes a commercial 3D computational fluid dynamics (CFD) model, Fluent, to assess the airflow characteristics in ventilated and air-conditioned archaeological tombs of Pharaonic Kings in the Valley of the Kings in Luxor, Egypt. It is found that the optimum airside system design can be attained, if the airflow is directed to pass all the enclosure areas before the extraction with careful selection of near wall velocities to avoid any wear or aberration of the tomb-wall paintings. Still all commonly known factors and evaluation indices have the shortage to describe the influence of the recirculation zones on the occupancy zone of the visitors and also on the fresh supplied air. The mode of evaluation should assess the airflow characteristics in any tomb passage according to its position in the enclosure and the thermal pattern and air quality. The tombs of Ramses, 7th, 4th, 5th & 6th are investigated, these are commonly known as KV1, KV2 and KV9. This work raises several questions in the room airflow motion prediction techniques. This paper represents the results of an ongoing evaluation of a CFD based on computer models for predicting room airflow distribution in the tombs of the Valley of the Kings in Egypt.
