Location: 2170 Gleason
Phone: 585-475-5604
Facilitator: Dr. Risa Robinson
Description/Projects:
Particle Image Velocimetry (PIV) is used to record images of flow
fields for comparison to numerical simulations. The system currently in
place at RIT consists of a high speed camera and pulsed copper vapor laser
(450 nm wave length) with fiber optic delivery, a 3 dimensional light
sheet, and multiple lens options to optimize the field of view. Images are
processed with commercially available software (VisiFlow, Oxford Lasers,
UK) using a cross-correlation technique. Data acquisition is controlled
using National Instruments hardware and software (LabView), equipment that
is available due to NSF grant #0088779. A hydraulic optical bench is
available to minimize vibration errors along with a sandbox mounting unit
to isolate the pump. Currently, hollow casts replicas of the human lung
which were manufactured out of polyurethane from MRI scans at the
University of Irvine, California, are being investigated. The experimental
rig required to mount the casts and traverse the velocity planes at
different angles is currently being designed and fabricated as part of a
Multidisciplinary senior design project and funded by Gleason Research
Foundation Grant. Future plans for the laboratory include integration into
the undergraduate curriculum through the Aerosol Mechanics technical
elective/graduate course and Fluids I lab.
