Thermal anemometry grid sensor for flow velocity measurement in the subchannels of a fuel element mock-up during dry-out

Arlit, M.; Schleicher, E.; Hampel, U.

For the determination of steam velocities in the subchannels of a fuel element mock-up during dry-out no suitable measurement techniques are available under the given boundary conditions of high temperatures and restricted accessibility. The newly developed thermal anemometry grid sensor closes this gap. Within the paper applied methods, technological aspects as well as a special calibration procedure for the measurement in superheated steam are presented.
