Instrumentation Details

Temperatures were measured with 0.51 mm (0.02 in) nominal diameter bare bead, type K thermocouples. Thermocouples and interior video cameras ("coolcams") were arrayed as follows:

 

 

The radiant heat flux at the floor of the living room was measured with a water cooled, Schmidt-Boelter type heat flux transducer. The transducer was equipped with a sapphire window to exclude convected heat flux. The view angle of the transducer, with the sapphire window installed, was approximately 150o. The radiant heat flux transducer was installed through the floor of the living room in order to protect the cooling and data lines from fire and physical damage. The face of the transducer was parallel and flush with the upper surface of the floor.
