INFLUENCE ANALYSIS OF NEUTRAL PLANE ON VENTILATION IN WORKSHOP

This paper analyzed the influence of neutral plane on natural ventilation in workshop. For several typical heights of neutral plane of a molding workshop, its influence on ventilation was simulated by means of CFD. In designing natural ventilation, to coordinate the dimensions between the inlet and outlet openings and to play down the neutral plane properly may be the effective measures to increase ventilation efficiency. In supervising ventilation, the cooperation should be intensified between the inlet windows, the secondary windows and clerestories in order that airflow short-circuits may be avoided.
