Laws of Radiant Heat Transfer
- An accessory designed to experimentally
investigate the laws of radiant heat transfer and radiant heat
exchange. The application of the laws to both heat and light radiation
are demonstrated using a radiant heat source and light source. Two
appropriate detectors, light filters, target plates of different
Emissivity and aperture plates each mounted on suitable carriages on a
parallel graduated track, and allow simple and rapid experimental
procedures.
- The electrically heated matt black
radiant heat source has an effective diameter of 100mm. and is fitted
with an integral thermocouple to record its surface temperature.
- A radiometer detects the heat flux
directly in W/m2 from either the source, a combination of four plates of
different Emissivity (two matt black, one grey and one polished) or
between a slot formed by two moveable cork faced plates. Each plate of
different Emissivity incorporates a surface thermocouple for temperature
measurement.
- The diffuse light source comprises a
low voltage filament lamp within a rotatable enclosure (180º) that can
be located on the parallel track in place of the heat source.
- A lightmeter recording directly in lux may be located in place of the radiometer in order to measure incident intensity.
- Supplied filter plates of varying
opacity and thickness can also be mounted on the track to demonstrate
the laws of light absorption.
