SPECIFICATION

Introduction: The equipment consists of a centrifugal fan with a vertical outlet duct. At the top of the duct there is 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 (T10) attached to the wall of the cylinder, at mid position, enables the surface temperature to be measured under the varying operating conditions.A K-type thermocouple (T9) in the outlet duct allows the ambient air temperature to be measured upstream of the heated cylinder. PID controller allows rapid heater’s temperature set-point achievement and control to ±0.1°C.

 


Specifications: A small-scale accessory to introduce students to the principles of combined convection (free and forced) with radiation from horizontal 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 100W.K-type thermocouples measure the air temperature upstream and the surface temperature of the cylinder.Air flow velocity through the duct, under computer control.A comprehensive instruction manual is included.
