They are con- nected to a PC through a Fluke Hydra data acquisition unit An additional thermocouple is used to measure the tem perature of the surroundings. The row of thermocouples second from the right is placed exactly under the centerline of the plate. The other thermocouples are distributed uni- formly in the cross-section of the box. The dimensions of the thermocouples are much smaller than those of the enclosure, therefore the disturbance to flow should be small.
