• Self-contained, bench-top mounting
• Includes three of the most common heat transfer surfaces – flat plate, pinned and finned
• Simple and safe to use
• Thermocouples and a sensitive anemometer measure temperatures and air velocity – shown on a digital display
• Additional hand-held thermocouple probe included – to measure temperatures along the length of the pins and fins of two heat transfer surfaces
• Variable speed fan and variable power heat source for a range of tests
• Can connect to TecQuipment’s Versatile Data Acquisition System (VDAS®)

Free and Forced Convection

Description

Experiments

The bench-mounting equipment includes a vertical duct that holds the chosen heat transfer surface and all instruments needed.

• Comparing free and forced convection for different surfaces TecQuipment include three different common heat transfer surfaces with the equipment:
• A Flat Plate

• Comparison of free convection from vertical and horizontal (finned) surfaces
• Comparison of heat transfer surface efficiency

• A Pinned Surface – similar to a tubular heat exchanger

• Comparing the coefficient of heat transfer and Nusselt
Number for forced and free convection

• A Finned Surface – similar to the fins on air-cooled engines or electrical heat sinks

• Temperature distribution along finned and pinned surfaces Each surface has its own
