A computational model of mechanical shaft of existing Seoul subway tunnel was analyzed in this research. The airflow in the sharft and the tunnel was investigated to find installing location of a guide vane. The numerical analysis characterized the aerodynamic behavior and performance of the airflow by solving three-dimensional turbulent Reynolds-averaged Navier-Stokes equations. ANSYS CFX software was used for the computations. The airflow in the ventilation shaft of the tunnel was investigated by analyzing the mass flow rate. The computational results showed the number and proper installing location of the guide vanes in the mechanical shaft to install the guide vane.

Tenter machines are used in the process of drying fabrics in textile industry. The lengths of wet fabrics are stretched on a tenter using hooks all around the perimeter of a tenter frame. The edges of fabrics are fixed to dry the fabric to retain its shape and size. The nozzle system of a tenter is important in the process. A tenter nozzle system is investigated to design nozzle structure and shape which has uniform flow velocity. The domain is studied to understand airflow characteristics inside the tenter chamber were analyzed by using ANSYS CFX. The developed nozzle system which has uniform velocity is designed in this study.

Working environment of plant workers needs to be improved due to increasing demand on the comfortable working condition. The thermal flow of an automotive plant in terms of comfort index was analyzed by using ANSYS-CFX software. The working environment was investigated with/without ventilation systems. Numerical analysis was accomplished to improve thermal flow stress by installing ventilation fans near the thermal stress concentrated field. Additional ventilating fans system and existing conditions were compared by numerical analysis.
