| description | In the present study, the application of computational fluid dynamic (CFD) to analyze air quality and thermal distribution in the workshop room with the multiple heat sources are investigated. In numerical study, a three-dimensional of a single-phase turbulent flow model is employed to analyze temperature distribution and fluid flow in workshop room. The initial and boundary conditions of the models are based on the experimental data. By solving the equations of continuity, momentum, and energy, the velocity and temperature distributions of air within workshop room are presented. It was found that the predicted air temperature and air velocity within the workshop room are consistent with the experimental results. The ventilation system positions and the installed position of equipment inside the workshop have significant effect on suction force which results in the accumulated heat and transport air pollution within the workshop room. The obtained results of the study are expected to lead to guidelines that will allow the designing the ventilation of air-cooling system to transport air pollution and accumulated heat for large workshop room coupled with multiple heat sources.
