FEATURES OF GAS DYNAMIC PROCESSES IN MEDIUM AND HIGH PRESSURE GAS NETWORK SYSTEMS FOR TRANSPORTATION THE GAS-HYDROGEN MIXTURES

The patterns of gas dynamic processes in the case of transportation of gas-hydrogen mixtures with different volume fraction of hydrogen in medium and high pressure gas network systems with the same flows and energy consumption for the elements of the supply system as in the case of pumping natural gas were established by means of mathematical modelling. Predictive indicators of change the energy parameter of gas network systems depending on the volume fraction of hydrogen in the gas-hydrogen mixture were obtained.
