Distribution of temperature and humidity of air in a dog heading gallery ventilated by forcing duct ventilation

Authors: B. Nowak, A. Sinha

With reference to (Nowak & Sinha, 1997), a set of equations at steady state condition has been presented describing the variation of temperature and humidity of air in blind heading galleries with forcing auxiliary duct ventilation, where the duct line has been treated as a leaky conduit in which leakage air is being distributed through out its length in continuous manner.

Based on the obtained mathematical model, a computer program for calculation has been developed in FORTRAN-77 as per given flow algorithms.

Exemplary numerical calculations oi tempet&toie and specific humidity of air. both in the duct line and in the blind heading gallery as well as intensity air flow have been presented in graphical form in 3 figures.
