The Natural Convection and Radiation equipment allows the study of heat transfer at different pressures and vacuum. It shows the differences between radiation and natural free convection.

A small heated element hangs in the centre of a pressure vessel. The heater has a matt black surface.

Attached to its surface is a thermocouple to measure the temperature.

The vessels inside is also black, and it has a thermocouple fitted to its wall to measure the temperature in the vessel.

It allows students to find the emissivity of a surface and verify the Stefan-Boltzman equation.

It also gives students an understanding of the non-dimensional characteristics using Nusselt, Grasof, Prandtl and Knudsen numbers.

Instruments and a digital display measure and display the temperatures, pressures and power to the element.

To give accurate measurements of pressure and vacuum, the equipment has two different pressure transducers - one for pressures above atmospheric and one for pressures below atmospheric.

The vessel may be charged with compressed air up to 1 bar (gauge) or evacuated down to about 5 Pa (absolute). Students can extrapolate the results down to a total vacuum (no convection).

This allows them to isolate the heat transfer by radiation.

Included is a vacuum pump, and a regulator for an external compressed air supply (up to 10 bar).

The system includes a pressure relief valve to protect the equipment and the user.
