Acoustic Absorption Measurements for Characterization of Gas Mixing

  title={Acoustic Absorption Measurements for Characterization of Gas Mixing},
  author={Aurelien Cottet and Tim C. Lieuwen},
Controlling and/or monitoring the degree of mixing between constituents of a multicomponent media is a key problem in a variety of applications. Monitoring such mixing processes necessarily requires capabilities for quantification of the level of “mixedness.” However, quantification of molecular mixedness levels, as opposed to macroscale mixture uniformity, is difficult. This paper demonstrates the use of acoustic absorption measurements to characterize an average level of molecular mixedness… 
A prototype acoustic gas sensor based on attenuation
Acoustic attenuation provides the potential to identify and quantify gases in a mixture. We present results for a prototype attenuation gas sensor for binary gas mixtures. Tests are performed in a

Ultrasound sensor for gas concentration measurement
In an anesthesia machine, there is a need to monitor the anesthesia concentration that is being delivered to the patient, mainly to stop and flush the system in case of fault but also to control th


Theory for a gas composition sensor based on acoustic properties.
The concept for a gas composition sensor is demonstrated theoretically for nitrogen-methane-water and hydrogen-oxygen-water mixtures and it should also be possible to use the concept for mixtures of more than three components, if the nature of the gas composition is known to some extent.
Quantification of mixing and mixing rate from experimental observations
A new measure of mixedness, based on entropy considerations, and a related mixing rate are introduced. It is argued that the time rate of change of the mixedness is proportional to the mixing rate.

Vibrational Energy Exchange between N2 and CO. The Vibrational Relaxation of Nitrogen
The vibrational energy exchange N2(v=1)+CO(v=0)=N2(v=0)+CO(v=1) should be fast, due to near resonance of the energy levels. We have studied the rate of this exchange relative to the rate of energy
