THERMAL COMFORT PREDICITON AND ASSESSMENT IN VENTILATED ARCHAEOLOGICAL TOMBS, KINGSVALLEY,LUXOR

Abstract

The tourism industry is one of the main industries Egypt is economically relying on nowadays, thus a high degree of concern was devoted to its enhancement. As the Valley of the Kings, Luxor, Egypt is one of the most important attractions in the world due to its uniqueness. The theme of this research was proposed by ministry of culture and the supreme council of antiques.

The following work is meant to investigate and assess the human thermal comfort inside the three tombs KVI, KV9, and KV62 in VALLEY OF THE KINGS, LUXOR for different proposed mechanical ventilation configurations. As KV62 (Tutankhamen tomb), is the most famous tomb in the world because of the treasures it held intact for over three thousand years, therefore the study has been focused on KV62.

Throughout the present work the number of visitors, outside air conditions, and different mechanical ventilations configurations were studied for the three tombs •, using FLUENT® 6.2 CFD (Computational Fluid Dynamics) package.

The thermal comfort prediction through this work was based on the PMV

1 • (Predicted Mean Vote) model and the PPD (Percentage Predicted Dissatisfied) model.

' The CFD modelling techniques solved the continuity, momentum, energy, and species transport equations in addition to k-e model equations for turbulence closure. The SIMPLEC algorithm is used for the pressure-velocity coupling and a second order upwind scheme was used for discretization of the governing equations. Mesh sizes used in the present work exceeded 1,400,000 mesh volumes in one case, and all mesh sizes were above 100,000 mesh volumes which allowed better and meaningful predictions of the flow regimes.
