Abstract (en)
[origin: EP1777505A1] Mathematical model for determination of non-linear temperature profiles for thick wall engineering components e.g. high temperature fluid transfer pipes, turbine shafts considers the wall as a composite of parallel layers each with non-steady state in- and out-heat flows, calculates a mean temperature for each layer from an instantaneous heat balance, and from integration of these produces values for the wall temperature at given depths. The technique considers a generally cylindrical thick wall as comprising a series of concentric layers e.g. 1-10, where layer 1 is in contact with a process fluid. The system calculates heat transfer coefficients and then sequentially computes mean temperatures for the layers, by repeated application of the algorithms.
