Fremgangsmåte og system for sanntids-estimering av strömningsmodus for en flerfasefluidström i alle punkter i et rör

摘要

- m method and system for estimating in time r olc the method of the discharge at all points of a pipe of the structure of efinie by a certain number of parameters of the structure of a multiphase fluid stream of efinie by a plurality of magnitudes physical. - it is in the form of a neural r network not lin eaire with a layer of between ee with as many between ed as the parameters of the structure and physical magnitudes, an output layer with as many outputs as parameters n ecessaires to the estimation of the method of the discharge and at least one layer interm ediate. It constitutes a learning base with the tables pr ed efinies connecting diff erent values obtained for the data ed of the output to the corresponding values of data ed of between ee, and it erations etermination by factors eration corresponds to the activation function making it possible to connect the values in the tables of data ed of between ee and output. In order to avoid the singularity data ed the output of the r network, which can distort the etermination corresponds eration factors, there is a sorting to dispose of data ed not relevant. The main advantages of the m method are: simplification of the mod ical modeling and gain period - applications, for example, to the r embodiment simplified ee of the hydrodynamic modules that can be int egrer, for example, to the tools of mod ical modeling.
