Fastest Modified Model of Hardy Cross Method for Ventilation Network Analysis of Mines (Second Conflation Model)

Ventilation network design is done in manual and computerized methods. A computerized method is based on mathematical approximate methods. Several algorithms were presented in mathematical approximate methods for analyzing water distribution and ventilation networks. Hardy Cross method is the most common model of the mathematical approximate method for analyzing ventilation networks in mine. For faster convergence to at the final result of Hardy Cross method were presented other models such as Wang model, conflation model, and Newtonian models (First, third and sixteenth). An initial review of the Hardy Cross method and its modified models is performed in this paper. Then first, third, and sixteenth modified models of Newtonian are presented for more accurate analysis of ventilation networks in mines. Finally, the second conflation model will be presented as the fastest modified model of the Hardy Cross method to achieve the final result.
