Facility
Rain Erosion Tester (RET)
Lab test from 40 - 100 m/s (plan to extend to 250 m/s)
Water jet radius ~2 - 4 mm
Rotation disc to cut water jet into individual water segments
Sample holder to enable curved samples, an impact angle from 15 degrees to 90 degrees
XYZ stage flexibility of performing several tests by making use of single test configuration
Two-phase wind tunnel
Water droplets as the dispersed phase, and wind as the carrier phase
Dimensions feature a .75 x .75 m cross-section and 4 m length
Control of water droplet content & wind speed (up to 10 m/s)
Incorporate water droplets in the air, simulating rain
Mechanism to remove water at the end of the loop
Hot wire probes and CTA for measuring turbulence
MATLAB for post-processing of data
Keyence Optical Microscope VHX-7000
4K Fully-Integrated head
4K CMOS image sensor
High-speed auto-focus stage
Focus view camera
Optical shadow effect mode
