SPHERICAL RESONATOR SPEED OF SOUND MEASUREMENTS OF NEW alternative GAS MIXTURES Fernando J. Pérez Sanz Universidad de Valladolid Spain
Motivation of the study • Depleting of fossil fuels reservoirs. • Increasing prices of fuels • Environmental problems • Global warming • Greenhouse effect • Acid rain • New fuel are being developed • Mixture properties recuired • Heat Capacities • Equation of State
Methods Thermodynamics • Speed of sound is an important thermodynamic parameter from which heat capacities and EoS can be measured. • Speed of sound is fitted to a Virial equation:
Methods Acoustic Resonance • Determination of radius by acoustic resonance in Argon
Future work • Coal Mine Methane • Biogas Mixture. • CO2-N2 Mixtures
