Numerical and Experimental study of the indoor environmental Conditions of a large Athletic hall (wrestling hall) using ansys 15

Abstract

This study investigates numerically and experimentally the environmental conditions prevailing in a large mechanically ventilated athletic hall, with the aid of the computational fluid dynamics by ANSYS 15 program. The indoor space of the building was simulated in the ANSYS 15 program environment and the model results were validated against experimental data collected during a 7-day campaign in the hall. The measurements included airflow characteristics at different locations of the indoor space, as well as surface temperatures of the indoor materials. Having obtained good agreement between experimental and numerical results, different scenarios were applied in the model to investigate the environmental conditions prevailing in the hall under different ventilation and occupational conditions. These regard air-conditioning and cooling modes, as well as empty and full hall during an athletic event. The velocity, temperature and relative humidity were studied and results revealed dynamic behavior of the fields, significantly altering with the different considered cases.
