Water Channel/Water Tunnel

Laminar Flow Water Channel

The Laminar Flow Water Channel is used predominantly for undergraduate student experiments in the AERSP 305 laboratory course, and is popularly featured during many department tours. Course-related experiments include determining fluid dynamic lift force, drag force and pitching moment on a 3D model, wake vortex visualization behind an airfoil, general flow visualization around a fully (or partially) submerged vehicle, and comparison and testing of various visualization techniques.

Research has also been performed in this facility, some of which involves boundary layer growth, LDV measurements, hydrogen bubble visualization, ocean paravane development and testing, and preliminary development of micro-scale water turbines.

Garfield Thomas Water Tunnel

Located in Penn State's Applied Research Laboratory, the Garfield Thomas Water Tunnel (GTWT) is the U.S. Navy's principal experimental hydrodynamic research facility.

The GTWT is a 48-inch diameter, closed-circuit, closed-jet water tunnel used for a variety of tests: steady and unsteady forces and moments, optical flow field surveys, pressure distributions, cavitation performance, noise and vibration measurements, flow visualization, torque, and thrust.
