Water Channel I:

The water channel is a recirculating, free-surface channel with a test section length, width, and depth of 4.9 m (192″), 0.93 m (36″), and 0.61 m (24″), respectively.  The top speed of the tunnel is 0.25 m/s (0.6 mph), which leads to typical Reynolds numbers of O(104). The channel uses two honeycomb sections and five screen sections to condition the flow to be uniform with low turbulence intensity of less than 1%.  This facility is located in Packard Laboratory, room 174.

Water Channel II:

The water channel is a recirculating, free-surface channel with a test section length, width, and depth of 4.9 m (192″), 0.61 m (24″), and 0.51 m (20″), respectively.  The top speed of the tunnel is 0.25 m/s (0.6 mph), which leads to typical Reynolds numbers of O(104). The channel uses one honeycomb sections and four screen sections to condition the flow to be uniform with low turbulence intensity of less than 1%.  This facility is located in Packard Laboratory, room 172.

Bio-Inspired Motion Control:

A wide range of motion control devices including DC motors, stepper motors, servomotors, and piezo-actuators are programmed with open-loop and closed-loop control.  This is used to study oscillatory, bio-inspired motions of hydrofoils and the subsequent flows and forces they produce.

Closed-Return Wind Tunnel:

The wind tunnel is a closed-return Engineering Laboratory Design (ELD) tunnel with a 0.46 m x 0.46 m x 0.61 m (18″ x 18″ x 24″) test section.  The top speed of the tunnel is 37 m/s (82 mph), which leads to typical Reynolds numbers of O(105). The tunnel uses one honeycomb section and two screen sections to condition the flow to be uniform with low turbulence intensity of less than 1%.  This facility is located in Packard Laboratory, room 372.

Open-Circuit Wind Tunnel:

The wind tunnel is an open-circuit Engineering Laboratory Design (ELD) tunnel with a 0.46 m x 0.46 m x 1.8 m (18″ x 18″ x 72″) test section.  The top speed of the tunnel is 28 m/s (62 mph), which leads to typical Reynolds numbers of O(105). The tunnel uses one honeycomb section and two screen sections to condition the flow to be uniform with low turbulence intensity of less than 1%.  This facility is located in Fritz Laboratory, room 235a.

Force Measurements:

Multi-axis forces/torque sensors are available for precision measurements of static models (e.g. the UAV above) as well as dynamic models using bio-inspired motion control (see above).  Typical measurements include lift, thrust/drag on bodies, stability derivatives for flight vehicles, and power consumption/extraction of dynamic bio-inspired devices.

Pisces I and II GPU clusters:

Pisces I is a six node cluster with Nvidia’s Tesla K80 GPU cards on each node.  This serves as a local cluster housed in Packard Laboratory, room 174a.  Pisces II is a single node with five NVIDIA Ampere A100 GPU cards, and it is part of the campus-wide Sol cluster.  These computational resources are used with our in-house 2D and 3D boundary element method solver employed for studying unsteady flows.

Flow Diagnostics:

Several mono and stereo Particle Image Velocimetry (PIV) systems are available to measure 2D and 3D flowfields produced by static and dynamic bodies in both the wind tunnels and water channels.  Smoke visualization is also available for the wind tunnels.
