H112D COMBINED CONVECTION MODULE teaching aid equipment Hydraulic Bench Equipment
Bench mounted accessory that allows experimental investigation of both natural and forced convection from a heated cylinder in a cross-flow configuration. The surface temperature of a duct mounted, matt black cylinder may be varied over a wide range; thereby allowing the increasing effects of radiant heat transfer to be investigated as the temperature is increased.
A variable velocity airflow within the small diameter circular duct is provided by an integral centrifugal fan and allows the effects on convective heat transfer from the cylinder to be investigated.

An integral thermocouple on the surface of the electrically heated cylinder allows surface temperature to be measured at all operating conditions. This combined with a duct-mounted thermocouple, heater input power measurement and in duct air velocity measurement allows all of the relevant parameters to be recorded . The heater power supply and temperature sensors connect to the Heat transfer service unit H112 while velocity is recorded on auxiliary instrumentation supplied as part of the H112D demonstration unit.
