Free and Forced Convection

Specification:

A bench mounted unit specifically designed to demonstrate the phenomena of free and forced convection and to measure temperature profiles from three different heat transfer surfaces
Comprises of a vertical air duct, with a transparent front for visibility mounted on a fan at the base of the duct, three heat transfer surfaces, airflow, and temperature probes
Technical data is included for each of the three heat transfer surfaces, which will enable students and researchers to compare practical results with theoretical analysis for free and forced convection
Three heat transfer surfaces supplied:

– a flat plate surface area 0.011m2
– pinned extended surface area 0.0525m2
– finned extended surface area 0.1414m2

Vertical duct incorporates a transparent front wall allowing complete visualisation of the process and identification of the airflow and temperature sensors
Each heat transfer surface is fitted with its own heater (240W) and thermocouples, to allow for easy interchange
All heat transfer surfaces incorporate guards to allow safe use outside of the duct for performing free convection experiments

Technical Details:

Relationship between surface temperature and power input in free convection
Relationship between surface temperature and power input in forced convection
Understanding of the use of extended surfaces to improve heat transfer from the surface
Determining the temperature distribution along an extended surface
Comparing characteristics of a vertical and horizontal flat plate in free convection
Determining the characteristic velocity, the Reynolds, Grashof and Rayleigh numbers for a flat plate in free convection
Comparing horizontal and vertical configurations for a finned exchanger in free convection
