Mesure des écoulements effet Doppler ultrasonique

Principle

The aim of this experiment is to study the relationship between the ultrasonic Doppler effect and the flow velocity or the Doppler angle.

Benefits

• Ideal for teaching the basics of the Doppler effect in fluids

• Experiment setup can be upgraded to perform experiments like flow mechanics and Doppler sonography
• Compact, easy to understand experiment setup

Tasks

1. Measure the frequency shift as a function of the flow velocity and angle of incidence.
2. Use this value to calculate the flow velocity.
3. Represent the frequency shift in graphic form as a function of the pump speed

What you can learn about

• Doppler effect
• frequency shift
• scattering
• Doppler sonography
