The slip velocity between the gas and sand particles has been measured using PIV.
- class="label">•
An erosion equation has been generated based on PIV results and erosion testing.
- class="label">•
Sand erosion is measured in a 76.2 mm ID standard elbow using ultrasonic probes.
- class="label">•
Predicted CFD erosion magnitudes are compared with UT erosion data in elbows.
- class="label">•
CFD predictions are within a factor of two of present and previous UT erosion data.
