Simulation and Analysis of Natural Gas Pipe Network for MNNIT (Allahabad) Staff Colony

In most of the developed countries and also in few of the metro cities of India, transportation and distribution of gas is through complex arrangement of pipe networks. These pipe networks handle wide range of pressures and flow rates of the fluids. The Pipe networks are more convenient, efficient and economical mode of transportation systems compared to the surface transport systems viz. Rail wagon, trucks etc. This fact is much more important for B class metropolitan cities like Prayagraj. Therefore, present study focuses on design, simulation and analysis of a pipe network for a small colony (MNNIT-Allahabad staff colony) of Prayagraj city. It first emphasizes on an optimum design of pipe network for proper supply of natural gas to the staff colony residents at low system operating cost. For simulation and analysis of the pipe network, two mathematical models i.e., Newton-Loop Method (Multidimensional) (N-L-M) and Newton-Loop Method (One-Dimensional) or Hardy-Cross Method (H-C-M) are implemented to find out the value of flow rate in each individual pipe and value of pressure at each node and further are compared to find out the best method out of the two to transport the LNG in the colony. The values of operating parameters obtained from both of the models are plotted to visualize the convergence rate and it is found that the N-L-M gives better convergence rate compared to H-C-M.
