Summary

The present paper was concerned primarily with the analysis, simulation of the air flow and thermal patterns in a mosque. The paper is devoted to numerically investigate the influence of person’s number on airflow properties in a mosque. The work focuses on airflow patterns, thermal behavior and carbon dioxide dispersion in a mosque where a large number of worshippers stand. The effectiveness of an airflow system is commonly assessed by the successful removal of sensible and latent loads from occupants in addition to attaining air pollutant at a prescribed level to attain the human thermal comfort conditions and to improve the indoor air quality. Commercially packaged floor mounted an air conditioning unit is a typical unit for such applications, due to the advantages it possesses over other types of HVAC systems and units. Many different cases for change in a number of persons, with also different distributions for the air conditioning units were investigated. Each case revealed the impact of person’s number on the overall comfort levels for worshippers. The performance of the air conditioning system is characterized by airflow patterns, temperature, relative humidity contours and CO2 concentration as well as the most commonly used comfort parameters PMV and PPD based on Fanger model; this is the main target during the present paper work. The study is carried out using computational fluid dynamics (CFD) simulation techniques as embedded in the commercially available CFD code (FLUENT 15). The CFD Modelling techniques solved the continuity, momentum and energy conservation equations in addition to RNG k – e model equations for turbulence closure.
