Transient heating of mine ventilation air with sensible rock energy
Conclusions 1. A method is now available for calculating the transient heat transfer to gases passing through geometries that can be approximated as slits. 2. For the cases studied:Three pass, parallel flow through a number of panels is significantly more efficient, energy wise, than one pass, parallel flow.Single pass, series flow through a given number of panels is roughly equivalent to parallel flow through the panels with three passes per panel. 3. Increasing the number of passes through a panel quickly increases the heat transfer efficiency. In the cases studied, three pass flow in either the parallel or series modes practically eliminates the influence of the heat transfer resistance at the rock-air interface.
