Free and Forced Convection

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


  • Includes three of the most common heat transfer surfaces – flat plate, pinned and finned
  • Thermocouples and a sensitive anemometer measure temperatures and air velocity – show 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

Each surface has its own built-in variable-power electric heater. Students choose which surface they need to test and fit it to the duct using simple fixings.

Two controls allow students to set different air velocities and heater power for a full range of tests.
