Processing time series data (velocity, shear stress) from the pulsewidth modulated-constant temperature anemometer (PWM-CTA)

摘要

The digital output from the PWM-CTA represents the short duration(e.g., 20μsec) true time average of the analog velocity or shearstress. The developed techniques to extract the moments of the velocity(or shear stress) distribution and to create a regular time series arepresented
