Facilities

The following facilities and equipment are available at LSU's WISE lab:

Laboratory

New Open-Jet Hurricane Simulator at LSU: The open-jet hurricane simulator was recently built and calibrated to create wind profiles that mimic wind characteristics over open/suburban terrain. Different wind profiles can be generated with flow management mechanisms. The large-scale test section is 4m x 4m, capable of creating actual hurricane winds at high speeds. In terms of instruments, the facility has two cobra probes for wind velocity measurements, two load cells, five accelerometers, four magneto-rheological dampers, a shake table, a laser sensor for displacement measurements, a shake table, and a 256-channels pressure measuring system to be used with the open-jet simulator independently from the instruments available at the wind tunnel.

LSU Wind Tunnel Laboratory: This laboratory includes two test sections: one can be used for aerodynamic studies while the other is modular for boundary-layer studies. The test sections are 2′ x 2′ x 8′ and 2′ x 3′ x 10′ (aerodynamic) and 3.5′ x 4.25′ x 25′ (boundary-layer), respectively. laboratory is equipped with a Laser-Doppler Velocimetry (LDV)) system for point-wise measurements of up to two velocity components, cobra probes for three components of velocity measurements, and a High Resolution Digital Photography (HRDP) system for visualization studies, pressure scanning system capable of sampling up to 128 pressure taps, six component (three forces, three moments) sting balance for aerodynamic force measurements, and computer-driven data acquisition and traversing systems. A new fan with 50 horsepower has recently been purchased and the data acquisition capacity will be expanded.

Computational Facilities

Computational Facilities: High-end PCs are used in most of the numerical simulations. LSU has powerful computing facilities that are equipped with desktop computers devoted for student use. Engineering Software licenses include MATLAB, AutoCAD, ANSYS, ABAQUS, Visual BASIC, Visual C++, MS Office and different operating environments. The high performance computing (HPC) resources at LSU permit premium computing and support users with the best possible infrastructure to carry out their research. HPC@LSU provides system administration and consulting support for the Louisiana Optical Network Initiative (LONI) supercomputers. LSU's new supercomputer, SuperMike is superfast and super cheap. At the time of installation in August of 2002, SuperMike was ranked second fastest in the academic world and 11th fastest in the world. Model simulations that once took 30 days are now being completed in 24 hours.

Other Resources

3D Printer: The Department of Civil and Environmental Engineering at LSU has a 3D Printer that can be used to create any shapes with different materials. The 3D printer can be used basically for building aerodynamic features and architectural details at different scales for testing.

Portable, Hurricane-Hardened Meteorological Towers: LSU operates two mobile hurricane towers – Storm 1 and Storm 2 – which are designed to be deployed in hurricane zones to collect meteorological data during landfalls. Storm 1 is a 10-meter tower that consists of a structural steel lattice and a hinge in the middle to facilitate tower transportation in a folded position. Outrigger legs provide lateral support to the tower in the extended configuration. The tower is outfitted with RM Young wind sensors at heights of 2.5 meters, 4 meters, 5 meters, 7.5 meters, and 10 meters. In addition to the RM Young sensors, a U-V-W system and vertical anemometer are located at the 10 m height. Pressure, temperature, and relative humidity gages are also located at elevations of 2.5 and 10 meters. A precipitation gage is located at 2.5 meters. Six deep cycle marine batteries power Storm 1. These batteries provide the voltage necessary to maintain the data collection from all sensors as well as the DAQ, which operates a National Instruments Compact Field Point system. The system sampled data from the sensors at 20 Hz onto a removable flash card. Storm 2 is similar to Storm 1; however, it is a larger tower standing at a 25-meter height.

Wind Cannon Facility at LSU: The facility includes pneumatically actuated steel cannon with computer control that can fire, in a controlled environment, projectiles simulating wind-borne debris generated by hurricane force winds. This cannon can replicate the effects of high wind speeds for different types of simulated wind-borne debris, including multiple small pebble-like missiles, typical 2"x4" lumber missiles, and heavier (e.g., steel pipe) missiles. The facility allows accurate measurements of impact resistance and deformation of the impacted objects.

Flow Dynamics and Control Laboratory at LSU: The lab features active, multimode acoustic/vibration forcing and measurement capabilities for open- or closed-loop flow control. It is also equipped with a Stereoscopic Digital Particle Image Velocimetry (SDPIV) system capable of measuring all velocity components on a flow plane, a High Speed Digital Video (HSDV) system for time-resolved visualizations, a two-channel Constant Temperature Anemometry (CTA) system capable of point-wise, time-resolved measurement of up to two components of velocity, an automated calibration facility, high quality microphones & vibrometers and automated data acquisition and traversing systems.
