Water Channel

The circulating water channel is used for flow visualization, measurement of force and pressure distribution on submerged bodies, and propeller thrust and torque measurement. The test section has a free surface, and pressure can be varied from +6 psi to -12 psi. This allows demonstration of cavitation effects on propellers and hydrofoil sections.
