  2. Some of the data we ask for: • Where and when was the heat flux gauge calibrated? • What is W/cm^2 range of the gauge? • What is the OSU brand? • What is the Gauge brand?

  3. Vatell calibration estimated to be 9% cooler based on peak time

  4. Statistically significant factors based on 3 years of data.

  5. Recommendations • Develop a new panel optimized to have a good peak time to heat flux correlation • Use an IR imager to characterize heat loss of OSUs • Visit other labs, especially the outliers to gain understanding. Bring the IR imager • Develop a finite element analysis model of the OSU to better understand significant variables

  6. Recommendations (cont.) • Extend calibration equilibration time from 2 minutes to 3 minutes per step. Use average of 1L/Min steps before and after each increase

  7. Recommendations (cont.) • Extend calibration equilibration time from 2 minutes to 3 minutes per step. Use average of 1L/Min steps before and after each increase

  8. Recommendations (cont.) • Extend calibration equilibration time from 2 minutes to 3 minutes per step. Use average of 1L/Min steps before and after each increase • Re-establish OSU QA task group. Especially need members willing to participate in mini round robins within the group, collect data on more operational parameters, and be willing to participate in exchange visits.
