PERFORMANCE OF HOLLOW V PLAIN ELEMENTS, WITH AND WITHOUT REFLECTOR
This report measures the differences in emitted heat flux between hollow and plain elements. Of particular interest is the effect of a reflector placed at the rear of the elements on the emitted infrared output. Two types of element were tested FTE650W and FFEH600W. These were placed in the Herschel and analysed using the 3D Infrared heat flux mapping routine.
In this automated system, an infra-red sensor is robotically guided around a pre-determined coordinate grid system in front of the heater element under test. The sensor is a Schmidt-Boelter Thermopile Heat Flux Transducer with a design maximum heat flux level of 2.3 W/cm² and measures IR in the band 0.4-10 micrometres. The incident radiant heat flux recorded at each point is then saved and post processed to give a 3D representation of the infra-red heat flux emission.
The results are shown and discussed as part of this paper.
