Sample Activity

Simulation of Dendritic Solidification Solidification of crystalline materials often occurs dendritically (e.g., in castings). The image shows dendritic growth into an undercooled liquid of a pure material. The two-dimensional computation was performed using the phase-field method, which employs a single set of model equations for both the solid and liquid regions. Displayed are contours of the phase-field variable which tracks the diffuse interfacial region separating solid and liquid. In the figure the liquid region is light gray and the solid dendrites are dark gray. The figure corresponds to a late stage in the computation where the solid dendrites have almost reached the boundaries of the domain.

Vibration Research Laboratory

Mission:
The Vibration Research Laboratory serves as the focal point for research covering a broad spectrum of mechanical and biomechanical phenomena. State-of-the-art measurement, testing, and computational facilities provide the tools for the advancement of our understanding of vibration, acoustic and stress related problems in engineering science.

Facility:
The Laboratory occupies 1400 square-feet of ground-floor space in the
Engineering Building. The Lab infrastructure includes electrical hookups from 120V to 440 V, compressed air, water, and forced-air ventilation are available. Two vibration isolation tables are available to reduce environmental interference for precise measurements. The Lab combines the computational/simulation and measurement/testing capabilities in an efficient floor plan. Additionally, a well equipped student machine shop and other research laboratories are also located
in the Engineering Building.

Measurement/Testing Capabilities:

The Vibration Research Laboratory's test/measurement capabilities are aimed at vibration and acoustic measurement of mechanical and bio-mechanical systems. Controlled shaking capabilities (random, sine, and shock) from modest sized packages weighting hundreds of pounds to very small biological systems (such as a fly's eardrum) are available. A shaker and an environmental chamber can be combined to do “shake and bake” testing. The Lab's measurement capabilities are enhanced by our state-of-the-art non-contacting laser measurement systems. The Lab's two laser vibrometers can be used for precise, focused (10 micron measurement point) vibration measurements. In addition, traditional transducers (accelerometers, LVDTs, strain gages) are also available.

Heat Transfer Laboratory

The Heat Transfer Laboratory is equipped to perform experimental investigations of convection and conduction heat transfer. Thermal measurements are obtained with a variety of techniques using one or more of the available precision bath and N.S.B. traceable temperature standard calibration facility, IR thermography camera or holographic interferometry system. Fluid flow studies are performed using techniques of flow visualization and laser doppler velocimetry (LDV). Data acquisition and analysis is facilitated by PC based systems. Rheological measurements are used to characterize complex fluids, such as dense suspensions.
