Three-Dimensional Dynamic Numerical Simulation of the Holy Mosque Area

EasyChair Preprint 9865

Abstract

A significant development occurred in the Holy Mosque area in the last twenty years. To increase the capacity mosque and the surrounding hotels, thus accommodating visitors and pilgrims over the year to keep pace with the increase in the number of Muslims. Accordingly, the air envelope of the Holy Mosque continuously varies. These buildings' effect on the Holy Mosque's aerodynamics can be noticed. Consequently, new wind gusts appeared with different altitudes, directions, and intensities. Also, new dead zone (calm wind areas) occurred. A dynamic three-dimensional model has been developed using computational fluid dynamics CFD to simulate the Holy Mosque and its surrounding area. The model covers a square area of 1800m in length and comprises the Holy Mosque near its center and the main buildings surrounding the Mosque. The accuracy of the CFD model was verified by comparing its result with one of the wind tunnel studies. Some fixed locations have been selected within the Holy Mosque to study the development of wind velocity over the last two decades. The recent areas of wind gusts and dead zones were defined. Some solutions are recommended to enhance the aerodynamics of the Holy Mosque.

Keyphrases: Aerodynamics, CFD, dead zone, fluid-structure interaction, gust wind, wind envelope
