| Abstract: | A mathematical model has been set up for a region near the inlet of a
heating method based wetness measurement probe. By way of a numerical simulation an
analysis was conducted of the measurement error due to a non isokinetic sampling and an axial
deviation in the steam flow direction. The results of such an analysis provide useful data for the
design and engineering application of the heating method based wetness measurement probes. |
