Dense Gas-Solids Flow Measurements (85)
Problem: Reliable techniques are needed to measure velocity and particle concentration/distributions in dense loaded gas flows
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis Method Development
PNNL Solution:
- Evaluated electromagnetic millimeter-waves for the measurement
- Used a lab test loop with controlled flowing gas/solids mixtures (80-micron-dia. particles and loadings up to 20 vol%)
- Checked data correlation against ultrasonic and optical methods
Capabilities Employed to Meet Client Needs: Millimeter wave and ultrasonic measurements (sensor configuration, integration); data acquisition/signal processing (developing the electronics and software to process the signal and automate the sensor) and fluid dynamics (development of experimental flow loop and interpretation of measurements).
