Characterization of Five-Hole Probes used for Flow Measurement in Stack Emission Testing

May 17, 2018

Author(s):

Iosif I. Shinder, Aaron N. Johnson, Michael R. Moldover, Bernard J. Filla, Vladimir Khromchenko

We report progress towards the goal of reducing the errors in industrial smokestack flow measurements to 1 % by replacing S-probes with calibrated 3-D probes (...

NIST’s New 3D Airspeed Calibration Rig, Addresses Turbulent Flow Measurement Challenges

April 14, 2015

Author(s):

Iosif I. Shinder, Vladimir Khromchenko, Michael R. Moldover

Outdoor air flows and flue-gas flows in large conduits and large stacks have significant swirl and turbulence. Accurate measurements of such complex flows are...

Comparison of laser-based and monochromator-based thermodynamic temperature measurements

March 19, 2012

Author(s):

George P. Eppeldauer, Howard W. Yoon, Jorge E. Neira, Vladimir Khromchenko, Charles E. Gibson, Allan W. Smith

In this work, we describe the comparisons between the laser-based and monochromator-based radiance responsivity calibrations of a radiation thermometer. The...

Extension of the NIST spectral power-responsivity calibration service to 2500 nm

March 02, 2012

Author(s):

George P. Eppeldauer, Howard W. Yoon, Jinan Zeng, Thomas C. Larason, Jeanne M. Houston, Vladimir Khromchenko

The National Institute of Standards and Technology (NIST) is working to extend the upper wavelength limit of the spectral power-responsivity calibration...

Spectroradiometric Characterization of the NIST Pulsed Solar Simulator

August 20, 2009

Author(s):

Howard W. Yoon, Brian P. Dougherty, Vladimir Khromchenko

The spectroradiometric characterization of the NIST indoor pulsed solar simulator is described. The solar simulator has a flash duration of 36.4 ms and is...
