Combined Convection And Radiation

Specification of Combined Convection And Radiation

• A
  small-scale accessory designed to demonstrate combined convection (free
  and forced) and radiation from a horizontal heated cylinder. It
  consists of a centrifugal fan with vertical outlet duct at the top of
  which is mounted the heated cylinder.


• Comprises a heated
  cylinder mounted in a vertical air duct, with a fan at the base of the
  duct which can be used to provide a variable air flow over the cylinder.


• Heater rating 100 Watt at 24V DC.


• K-type thermocouples measure the air temperature upstream and the surface temperature of the cylinder.


• The air flow is electronically adjustable over the range 0 - 7 m/s by an variable speed fan.


• The air flow is manually adjustable


• The air flow rate is measured by a vane type anemometer in the outlet duct.


• The
  accessory is mounted on a PVC baseplate which is designed to stand on
  the bench top and connect to the Heat Transfer Service Unit without the
  need for tools.

Technical Details:

The
equipment consists of a centrifugal fan with a vertical outlet duct at
the top of which is mounted a heated cylinder. The mounting arrangement
for the cylinder in the duct is designed to minimize loss of heat by
conduction to the wall of the duct.

The surface of the cylinder is
coated with heat resistant paint which provides a consistent emissivity
close to unity. A K-type thermocouple attached to the wall of the
cylinder, at mid position, allows the surface temperature to be measured
under the varying operating conditions.

A variable fan blows air
through the outlet duct and a vane type anemometer within the fan outlet
duct allows the air velocity in the duct to be measured. The fan is a
variable speed fan with electronic control. On a manually adjustable
throttle plate allows the air velocity to be varied.
