Exploring the Venturi effect

3D ModelNoAI

The Venturi effect occurs when the velocity of a fluid increases as the area of the container it flows through decreases. The pressure in the tube decreases as the fluid flows through the narrow section due to this increase in velocity.

A simulation was performed to create this model which depicts streamlines within a tube. The lines are coloured to show that the pressure at the throat section is lower (blue) than the pressure at the inlet or outlet sections (red).

Particle movement is based on velocity measured during the simulation. The particles travel faster as the rate of flow increases in the narrower section of the tube. They slow again as the tube widens.

Simulated using OpenFOAM.
