Applications of dynamic gravimetric methods for fluid flow measurements and developing primary standards based on dynamic approach.
Developing and improving working standards for airspeed measurements, including Laser Doppler Anemometer and Pitot Static Probe systems.
Design and manufacturing new calibration systems including 3D airspeed probe calibrations, their traceability, and measurement uncertainty calculations.
Blockage effect corrections in wind tunnels, turbulence and its effect on airspeed measurements.
We used NIST's primary water flow standard to study the feasibility of accurately determining mass flow rates m dot of water "dynamically," that is from the

Exhaust flows from coal-fired electricity-generating-plants are determined by measuring the flue gas velocity at prescribed points in the stack cross section
A non-nulling gas velocity measurement apparatus performs a non-nulling measurement of gas velocity parameters and includes: a non-nulling pitot probe; gas valves in fluid communication with a different entrant aperture of the non-nulling pitot probe via a different pressure channel; receives
