This equipment has been designed to study Fourier’s equation in a one-dimensional system in steady-state conditions. It includes two cylindrical sections for heating and cooling that can be coupled to each other; furthermore some interchangeable sections can be inserted. Heating, cooling and intermediate sections are positioned coaxially inside cylinders of plastic material to minimize heat losses and to protect operators from scalds. A set of thermocouples installed at regular intervals enables to detect the temperature trend.
TRAINING PROGRAM
This unit enables to develop and analyze the following issues:
• Using Fourier’s equation to describe the heat exchange between solid materials
• Temperature trend during heat transfer by conduction through the contact surface between the same material or
different materials
• Determining heat conductivity of different materials
• Temperature trend during heat conduction through a flat wall of reduced section
• Insulating materials
