In the current work numerical and experimental study are conducted to investigate the flow behaviour and thermal comfort in climate-controlled conference hall situated at University of Anbar. In the first part of the study, numerical investigation is conducted to understand the impact of the air conditioning supply and extracts openings locations on the physical characteristics of the air flow within the conference hall. Moreover, the study investigates the optimal location of the air conditioning units within the system. In this work the main emphases are to study the flow dynamics of the air and the thermal behaviour inside the conference hall with large number of audiences inside it. Typically, the efficiency of an air flow system is evaluated by the successful removal of sensible and latent loads from the system under control. In addition, to maintain the level of air pollutant at a prescribed accepted level to assure the optimal human thermal comfort conditions. This will improve the indoor air quality and the thermal comfort for the audience which is the main goal of the present study. The numerical part of the study is carried out using computational fluid dynamics (CFD) simulation approach. To attain this part, commercially available CFD software ANSYS\Fluent is used. The numerical modelling techniques solved the continuity, momentum, and energy conservation equations. The k – ε model is used to tackle the turbulent nature of the flow studied in this case. The second part of this study is achieved by measuring the velocity, air temperature and relative humidity experimentally by means of the calibrated instruments. The validation of the used approaches is carried out through comparing the attained numerical and experimental results. Good agreement is found between the numerical and experimental predictions obtained during the present work. [ABSTRACT FROM AUTHOR] |
