    NUMERICAL RESULTS. Pipeline Network Simulation. The numerical routines of the simulator are applied to the network presented in Figure 2. This network is composed of 28 pipelines connected with 26 vertices. The lengths and diameters of the pipelines are given in Table 2. The absolute roughness of the pipelines is 46 m m and the thickness is 0. From the standpoint of mathematical physics, a CFD-simulator performs numerical simulation of steady and transient, non-isothermal processes of a gas mixture flow in long, branched, multi-line, multi-section gas pipeline network. Such simulation is aimed at obtaining high-accuracy estimates of the actual distribution (over time and space) of Cited by: 1.
