In this paper, we investigate the relative contribution of shock losses to the total pressure drop in a mine ventilation network. It is shown that for a specific class of mines it is necessary to consider the shock losses of mine airway junctions. This class includes mines with large airway cross-sectional areas and extended work areas. A comparative analysis of existing literature on
methods to calculate shock losses is conducted using ventilation system with parallel airways. Existing methods are compared with the results of 3D numerical simulation of airflow through junctions. Click here for the full paper on this topic.
