Thermal Energy Transfer Experiment

Topics covered:

- Thermal conduction

- Thermal radiation

- Thermal resistance

- Insulation

Principles and objectives:

Set designed to highlight the phenomena of thermal transfer

through conduction and radiation as well as the insulating power

of different materials.

The device consists of a plastic case which

serves, in addition to its storage function, as an adiabatic enclosure for the

conducting of experiments. It contains 2 steel blocks and 2 aluminum blocks

of the same size as well as 2 threaded plastic rods

for handling the hot blocks. The metal blocks can accommodate

temperature probes of 3 or 6 mm in diameter.

The experiments consist of heating the different blocks to different initial temperatures (using a water bath not provided), and recording the evolution of their respective temperatures over time until reaching a steady state. And this under the following conditions:

- Blocks in contact with each other: conduction

- Blocks separated by a thin air gap: radiation and, to a lesser extent, convection

- Blocks separated by 3 types of insulating materials of the same thickness.

The analysis, more or less in-depth depending on the objective of the lab, is carried out with the Scientific Workshop software.

Comments:

This lab is an excellent qualitative and quantitative introduction to the study of the different modes of thermal transfer as well as insulation methods based on their thermal resistance.
