LT-CH000 Cross Membrane Filter

Thermal tunnel is a device for measuring thermal conduction and convention, It is designed to demonstrate the phenomena of natural (free) and forced convection. The tunnel has a heating element and temperature sensor along with a fan to control the flow speed. All data is measured and logged to computer via a software.

Learning Objectives:

Understand the principles of thermal conduction and convection.
Learn the differences between natural (free) and forced convection.
Explore the function of heating elements, temperature sensors, and fans in thermal systems.
Measure and log thermal data using a computer software.
Study the behavior of heat transfer in different convection scenarios.
Gain practical experience with a thermal tunnel setup for measuring thermal phenomena.
