• Using Ultrasonic Anemometers to Evaluate Factors Affecting Face Ventilation Effectiveness
  1/1/2006 - Peer reviewed journal articles
  A test system was developed at NIOSH's ventilation test gallery to measure airflow using a three-axis ultrasonic anemometer. The gallery was used to simulate face airflow conditions in underground mines having a blowing curtain. Airflow data were used t...
• Experimental and Modeling Investigation of the Effect of Ventilation on Smoke Rollback in a Mine Entry
  1/1/2006 - Peer reviewed journal articles
  Results of diesel fuel fire experiments were conducted to determine the critical air velocity for preventing smoke rollback. Experimental results compared well with model predictions based on a computational fluid dynamics fire dynamics simulator.
• Measurement of Airflow in a Simulated Underground Mine Environment Using an Ultrasonic Anemometer
  1/1/2004 - Peer reviewed journal articles
  Reports on a test system and computer program developed for using a three-axis ultrasonic anemometer to measure airflow in a simulated mine entry.
