[0002] In the actual operation of the steam pipe network, due to the complex structure of the steam pipe network, it is difficult to accurately value the roughness of the pipe wall and the insulation of the pipe. With its transformation, aging, and changes in operating conditions, the physical parameters in the pipe network will Constantly changing, large calculation error and unable to carry out online measurement

In the calculation process of the pipe network model, the pressure drop correction coefficient is affected by the physical characteristics of the pipe wall, fluid properties and flow state changes, so it is difficult to ensure a good estimate of the pipe network pressure drop coefficient in the dynamic process
