  "abstract": "<p>Simulator algorithm for water networks based on loop method.</p>\n\n<p>Simulation of water networks by using the loop method and Newton-Raphson numerical method (wat_dem1.m) : the simulation starts with running the Matlab function wat_dem1.m</p>\n\n<p>There are given the nodal consumptions, the characteristics of the pipes, head value of reference main head node, inflows/outflows.</p>\n\n<p>sim_demo_pb.m - simulation of water networks by using the loop method and Newton-Raphson numerical method.</p>\n\n<p>determine_flowsi_pb.m - this function uses Depth First search to calculate the following variables: the loop incidence matrix Mlp, the topological incidence matrix Anp, initial pipe flows flows_i, chord/co-tree pipes.</p>\n\n<p>shortest_path.m - This function calculated shortest path between two nodes in the spanning tree.</p>\n\n<p>This simulator can be applied to any water network not containing non-linear controlling hydraulic elements although some &ldquo;minor modifications&rdquo; would be necessary in the various Matlab files such as :</p>\n\n<p>in sim_demo_pb.m at line 98 the number of loops l is 28, so for a different water network the number of loops would be different so it is better to change the number 28 with the letter l which stands for the number of loops. other &ldquo;minor modifications&rdquo; would be for example in the file determine_flowsi_pb.m at line 408, to remove nodes 65, 61, 62, 35, 34 and node 33 which are fixed head nodes but in a different water network these numbers may not mean anything. other similar &ldquo;minor modifications&rdquo;. This algorithm would benefit also from the addition of non-linear controlling elements based for example on the paper Alvarruiz et al.
